What is String Algae?

String algae are long strands of algae that attach to surfaces like rocks and pond walls. You might also see them floating in bunches. This algae naturally shows up in living ponds, especially those with fish and plants. In small amounts, string algae absorb extra nutrients and even help oxygenate the water. Plus, they provide shelter for tiny organisms that keep your pond in balance.

When It Becomes a Problem

While a little string algae is fine, too much can cause real trouble. Here’s how you’ll know it’s getting out of hand:

• Thick mats are floating on top of the pond.
• Algae is clogging your pond’s pump or waterfall.
• The water looks messy and uninviting.

Too much string algae can:

• Lower oxygen levels as it decays, making it harder for fish to thrive.
• Block sunlight and take nutrients away from other plants.
• Make your pond look untidy and less enjoyable.

How to Handle String Algae the Right Way

At FncPonds, we focus on keeping your pond clean in a way that works with nature. Here are some of our favorite methods to control string algae:

1. Remove It by Hand

Use a pond net, brush, or your hands to pull out large patches of string algae. It’s a quick way to make your pond look better and remove some of the nutrients that algae feed on.

2. Add Helpful Bacteria

Beneficial bacteria break down extra waste in your pond like leftover fish food, plant material, and fish waste. By reducing this waste, there’s less food for algae to grow. You can add these bacteria as part of regular pond care.

3. Use Targeted Algae Treatments

If string algae keeps coming back in specific areas like waterfalls or streams, try a spot treatment with a pond-safe algaecide, like EcoBlast. Just treat the problem spot—not the whole pond—to avoid upsetting the pond’s oxygen levels.

4. Install an IonGen System

An IonGen system releases tiny amounts of copper into the water. This makes it harder for algae to grow, especially in hard-to-reach areas. It’s safe, low-maintenance, and works well in most ponds.

Strengthen Your Pond’s Natural Defenses

The best way to fight algae is to make your pond’s ecosystem stronger. Think of it like this: if you plant enough flowers in a garden, weeds don’t have much space to grow. Here’s how to help your pond stay naturally balanced:

• Add more pond plants: Water lilies and floating plants block sunlight and use up nutrients before algae can.
• Use gravel on the pond floor: Small gravel gives koi and goldfish a place to dig, which keeps algae from settling.
• Let your fish graze: Koi and goldfish love to snack on string algae. You can skip feeding them now and then so they eat what’s in the pond.

Why Algae Grows in Spring

In Dallas, many pond owners notice algae blooms in early spring. That’s because the water is warming up, but your pond’s good bacteria haven’t fully kicked in yet. Don’t worry! Scoop out what you can and keep using beneficial bacteria. As your pond adjusts, the algae will start to slow down.

Be Cautious with Chemicals

Some pond owners try to clear up algae with chemical treatments. These can work fast, but they’re not always the best idea long-term. Chemicals can hurt the balance of your pond. If you do use them, always remove any dead algae so it doesn’t rot and lower the oxygen in the water.

Final Thoughts from FncPonds

String algae isn’t your enemy—it’s just a part of a living, breathing pond. The goal isn’t to get rid of all of it, but to manage it so your pond stays healthy and beautiful.

Quick recap:

• A little string algae is okay.
• Remove large patches by hand.
• Use helpful bacteria and add more plants.
• Try safe spot treatments or an IonGen system.
• Be cautious with chemical use.

Fish, much like humans, exhibit discernible behaviors, allowing you to understand their well-being. Learning to distinguish between positive and negative fish behaviors empowers you to act promptly, addressing any adverse condition before it escalates.

Let’s first explore the positive behaviors indicating your pond fish are thriving:

• Exploring the pond’s surface, signaling hunger.
• Frequent pectoral fin movements, especially when analyzing the water’s surface.
• Strong appetite.
• Consistent exploration.
• Socializing with other fish and avoiding solitude.
• Body flexing for better visibility.
• Foraging in the pond’s gravel.

When your fish display these behaviors, it’s a sign they are content and in good health. But how about behaviors that deviate from the norm?

Negative fish behavior indicative of distress include:

• Refusal to eat.
• Folding fins tightly.
• Lying at the pond’s base.
• Remaining immobile at the pond’s surface.
• Exhibiting reduced activity or floating idly.
• Exhibiting scratching or flashing.

Witnessing these behaviors warrants immediate attention. Here’s how to interpret and address these signs:

Loss of Appetite

When fish are indifferent to food or outright refuse to eat, consider evaluating water quality, particularly during peak summer months. Poor oxygenation in warm water or imbalanced nitrogen levels are common culprits. Introduce an aerator to enhance oxygen levels and conduct water tests to detect nitrate imbalance. Consider parasite infestations when water quality is optimal.

Fish Behavior: Clamped Fins

Fins held closely to the body symbolize discomfort, often attributed to water quality or parasitic infections. Start with a thorough water quality check, and if it’s satisfactory, seek parasite treatment solutions.

Lying at the Bottom

Fish resting at the pond’s bottom often signals high water temperature, elevated nitrate levels, or diminished oxygen levels. Initiate water tests and consider parasites if water conditions are stable.

Stiff Swimming with Folded Fins

This fish behavior typically denotes an advanced stage of discomfort, potentially a progressing parasitic infestation or bacterial infection. Start with water quality assessments and consider parasitic evaluations if water conditions are not problematic.

Piping at the Pond Surface

Gasping fish at the pond’s surface is a strong indicator of low oxygen levels or gill damage. Introduce an aerator and, if the behavior persists, assess for parasitic infections.

Fish Behavior: Reduced Activity or Idle Floating

While this is not an outright sign of illness, monitor oxygen levels, especially in warmer water with minimal water movement. Installing an aerator typically resolves this issue within hours.

Frequent Flashing

Occasional flashing or scratching is not alarming, but when it becomes a frequent sight, inspect the pond’s pH level or look for parasites.

By understanding and recognizing the various behaviors of your pond fish, you can swiftly address and rectify any issue, ensuring a harmonious, healthy habitat for your aquatic friends. Contact us for more information.

The post Figuring Out Dallas Pond Fish appeared first on FNC PONDS.

The presence of fish in a pond is the number one reason for creating a water feature in the first place for many pond owners. Many pond owners who have kept aquarium fish for years decide to extend their hobby to the outdoors, while others view fish as a beautiful enhancement to their water garden. Regardless of the reasoning behind it, you’ll be able to enjoy this satisfying hobby for years to come.

You might be surprised at the affection you develop for your pond fish, finding them to be just as cherished as your dog or cat. You might even decide to name them! And just like your furry friends, your finned friends require a bit of special care and proper nutrition to thrive and flourish. Educate yourself on how to feed koi and pond fish to ensure their well-being and longevity.

To Feed or Not to Feed

Feeding koi can be a delightful family activity. When you first introduce the fish to their new home, they may initially appear shy and disinterested in the food you offer, often seeking refuge among rocks and caves. You don’t have to be overly concerned about this behavior, simply sprinkle a small amount of food into the pond and step back. After a few minutes, their curiosity is likely to kick in, and they’ll start showing interest in the food again. Consistency is key when it comes to feeding, try to feed your fish at the same time and from the same location each time you visit the pond, and over time they’ll become accustomed to your presence.

Its important to remember that anything you feed your fish will eventually be broken down and processed through your pond filter. Therefore, its crucial to buy high quality fish food that is specifically designed for the species in your pond. Feeding the low quality food can lead to water quality problems such as green water, string algae, and overall poor water conditions.

A Special Treat

Some pond owners like to treat their fish occasionally to something fun like fresh watermelon, orange slices or mandarin oranges, and even Honey Nut Cheerios. If you want to do the same, keep the amount you give small and remember that the natural ecosystem of your pond has to deal with any unconsumed food left behind, so its important not to overfeed your fish.

Two Minute Rule for Feeding Koi

A good rule of thumb to follow is only feeding koi what they can eat within a couple of minutes. Remember, the decision to feed your fish is ultimately up to you as many pond owners never throw a piece of food into their pond. The natural ecosystem of your pond will produce enough food and nutrients for your fish to consume while also creating a balance between your plants and fish. If your fish are on the larger scale, they’ll need more food and might turn to your aquatic plants for a tasty snack if they aren’t getting enough food.

 Choosing the Best Food

Studies have been done comparing the digestion of protein from different sources in fish, revealing feeding koi fish proteins offers the best digested and absorbed protein for other fish. Essentially, fish eat fish.

Fish have evolved to consume others in their food chain, making fish proteins the optimal food choice for them.

Are Feeding Koi Plant Proteins Bad?

Plant proteins aren’t automatically a bad thing to feed your pond fish as they provide additional nutrition value like fiber and carbs. When used in combination with aquaculture proteins, plant proteins are a beneficial additive to your pond fish’s diets. Foods that list fish meal first and then wheat germ, soybean meal or corn gluten meal means its a perfectly acceptable and nutritious food for your fishy friends.  We use and recommend Aquascape Fish Food.

Assessing an Ingredient Label

Reading ingredient labels can be both exciting and potentially misleading for consumers. Some labels may showcase great ingredients and attention to manufacturing quality. Others might use tactics like ingredient splitting and foreign laws to confuse buyers.  Contact us for more information.

Maintain a Healthy Population

One of the best ways to keeping your pond healthy and balanced?  Don’t have to many fish!  We get it—it’s tempting to add colorful koi and goldfish to your water garden, but too much is not a good thing.  Too many fish creates excess waste in the pond water, which in turn can cause water quality issues. As a general rule of thumb, pond fish need 10 gallons of water for every inch of their length. So a 10-inch long fish needs 100 gallons. If you have five 10-inch long fish, your water garden should have at least 500 gallons of water. Keep in mind that your fish are going to grow so be sure to under-stock your pond in the beginning.

 Fish Need Clean Water

Your pond water should always be clean-smelling and have good clarity.  On occasion, the water might be green due to suspended algae, or slightly brown due to tannins. Algae is expected in the spring when the plants haven’t yet reached maturity for the season. Once the plants grow, they consume more nutrients from the water thereby starving algae of food to survive. Ponds in sunny locations experience higher algae growth, but this can be alleviated by shading the pond surface with waterlilies or floating plants like water lettuce and water hyacinth.

Keep in mind, algae isn’t necessarily a bad thing. Your pond fish will eat algae off the rocks in your pond so it’s good to have a little of the green stuff. Too much algae can become unsightly but can be controlled with various water treatments.

If you’re going to keep fish, it’s imperative that your pond have proper filtration. A mechanical skimmer is your first line of defense for removing unwanted debris such as leaves and twigs from the surface of the water. If left to decay in the pond, organic material can cause a host of water issues that could make your fish sick. The skimmer also houses the pump which circulates the water and helps to aerate the pond. A biological filter is positioned opposite the skimmer to create the beginning of a waterfall. This filter uses bacteria to break down pond wastes, converting them into less harmful compounds that can act as aquatic plant fertilizers.

Don’t Overfeed your Fish

Koi benefit from premium prepared fish food, but remember—they also feed on things like algae and insects—it’s part of what created an ecosystem pond.  When buying fish food, look for food that contains a high-quality protein along with stabilized multivitamins and probiotics. And most importantly, only feed your fish what they can consume in about three to five minutes. In the summer you can feed them twice per day, but in spring and fall you should only feed them once per day.

Following these three basic rules for keeping koi and pond fish will help ensure that your finned friends have a solid foundation to grow and thrive. You’ll enjoy hours of watching your colorful koi and goldfish swim around the pond, gliding here and there beneath the waterlily pads. It’s a great stress reliever and a perfect activity to enjoy a bit of nature in your own backyard with the family.

Among inexperienced Koi Fish seekers, one question looms early in the process of finding that perfect pond addition, pet or show quality? This is an inquiry often asked by breeders, but you may find yourself wondering, “how should I know?” or “why does it matter?”.

Well, when it comes to purchasing Koi, there are usually two categories of shoppers –those looking for pets and those looking for a prized collection. Just like in dogs or horses – bloodlines, markings, and size can determine the price associated with your Koi.

Understanding the difference between show quality and pet quality Koi – and how breeders arrive at those assessments – can significantly demystify the selection process for many new owners.

So, let’s take a look at the various groups of Koi to help better understand what is important to you and what you’re paying for when selecting Koi for your water garden.

Koi Fish: The Domestic Group:

The Domestic group is exactly what the name implies.  Attractive and healthy, this fish has been spared a long trip from overseas.  The bloodlines of most domestic fish are short, and the classic ancestral stock is not long ago. So, the fish are tough and of good quality. But with a lack of refinement comes a less refined look. Domestic, durable koi of average to good quality make wonderful, sturdy pets and are an enjoyable addition for your pond.

The Import Group:

Typically imported from Asia, these koi are more expensive than their domestic counterparts, but in general, they are more attractive. So, just like most things, fancier equals more expensive. Why are they more expensive?  Their prettier appearance is more desirable and the cost of shipping is high.

The Handcrafted Exotic Group:

The definition of handcrafted is to “make skillfully by hand” and as you can imagine there is a much higher price associated with anything “handcrafted”.  However, it is safe to assume that the type of koi owner looking for a handcrafted koi, is also the type of koi owner who doesn’t care about price, they simply need to have the best.

The grand champion koi is much like a vintage Italian race car, no one cares about the skills of the driver, just the beautiful car.  It’s a profoundly expensive fish that is bred, raised, and shown by a Japanese craftsman, then sold to a trophy hunter in America. No skills are called upon to buy a fish that already comes with a trophy- just a fat wallet.

Koi Fish: The Handcrafted Domestic Group:

Just like the Domestic Group above, these Koi are handcrafted right here in America. They are fast and beautiful. The comparison in koi is the hand-selected small import or domestic koi that goes on to take a trophy in a local show.

In this case, the owner of the fish chose it based on its assessed future quality and they raised it to sub-adult or adult status and put it in a koi show. There is a lot to be said about a triumph in a koi show with a fish you chose and raised by hand. A true testament to your skillset to judge fish, to identify quality, and to provide the kind of husbandry needed to produce a champion from a small fish you hoped was a prized jewel.

The “Ordinary” Group:

The ordinary, unadorned and unembellished Koi is the last group of Koi on the market. There’s nothing wrong with an “ordinary” koi, but exceptional colors or patterns don’t generally occur in this group. These fish are certainly pleasant to own – just recognize that they aren’t going to win any shows.

Novice koi collectors often mistakenly assume that a koi with orange pigment is adequate to be a proper koi, but that isn’t the case. The all-yellow koi, called the Lemon Ogon, is wildly popular and easy to produce. It could be considered one of the finest koi of this ordinary group because it is abundant and not unlikable to own.

Often times breeders will sell the poorest of their culled baby koi into the fish bait market, and as feeder fish for consumption by larger fish in pet shops. The common alternative is to either bury the fish, or sell them as pond grade koi.

What Do These Different Groups Mean?

What this ultimately means is that there are different pedigrees of koi to choose from when purchasing your next finned friend. But more importantly, acknowledging there are very different types of koi owners as well. But you want to know the amazing part?

While the owners of economy koi are unlikely to expect all koi to be low cost and lower quality – the converse is not true of some of the folks who keep and show the finest koi. It’s important to remember at the end of the day, there’s a vast difference in the way koi need to be kept, and the way they are kept by the koi aficionados.

How are your Koi this spring?  Ahhh, Spring. Mother Nature is blowing a warm wind through the air. Flowers aren’t the only thing blooming, so is young love. It’s popping up everywhere, not just in the tulips and pansies, but also in your pond. That’s right, all that splashing around and displayed exuberant behavior is not your fish fighting, they are dancing around the idea of… spawning.

Spawning? Yes, you read that right. Koi fish, just like any river fish with a developed mechanism for river life, scatter their eggs everywhere rather than laying them in a neat and tidy nest, like other pond fish. The warming of the water, followed by longer hours of daylight, set off a biological trigger that “creates the mood”, if you will. These changes in ambience cause hormones to be released in the fish, causing the female to become full (gravid) of eggs and the male poised and ready for fertilization.

Surprised? Don’t be. Consider yourself lucky to have a front row seat observing the ‘wild ways’ of wildlife right in your very own backyard!

Shall we Dance?

The peacefulness of early morning is about to get a lot more interesting, now that Spring has sprung. You may notice an increase in activity in the pond during this time, particularly with your Koi chasing each other around the pond. The larger the fish, the more disruption that can occur. Upsetting pots, rocks and roots- in their rambunctious rowdiness, all in the name of love. The female Koi, she would be the “rounder” one, is “driven’ by one or more males, and even on occasion, during all the excitement, other females may partake in the pursuit of the female laying her eggs.

We know this sounds hectic and not terribly romantic, but it has to happen in order for the female to release her eggs. Female Koi do not have the ability to push their eggs out with abdominal muscles, so they depend on the pressure of being pushed around the pond, sometimes even into rocks or plant material. The males will even bump their heads into her flanks to provide a little extra “oomph” to help the process along.

One thing to keep in mind, spawning is a natural process, without setting up a “natural” habitat in your pond, it is highly unlikely, to almost impossible for her to spawn on her own. We aren’t suggesting a blanket of rose pedals, but the mood can be set by the environment for fish, as much as for humans. In plain liner ponds, with no decorative features or natural elements, the fish have no obstacles to spawn against and they may require artificially induced spawning hormones. Your Koi also appreciates a little privacy, so good plant and rock coverage that gives them a place to hide helps.

Looks like a (Koi) fight!

Most pond owners who are new to this arena, are shocked to see their Koi “fighting” each other one day, when in fact they are NOT fighting but rushing at each other in a spawn. Understandably, some females during this “amorous roughhousing” will endure a few abrasions, mainly on the face and flanks. These should quickly heal under two conditions.

First, be aware of your male to female ratio. Ideally, there should be two males to every female. Anything higher, means she’s the only gal in the pond, and she’s pretty much rushed all day. (C’mon ladies, you know how annoying this can be) Also, remove any female that gets run for more than four hours.

Secondly, water quality is important. Neutral, healthy water with little to no nitrogen will help to heal any injuries. If the water is too high in ammonia, nitrate or the pH is sagging low, the female will not heal well and infections are inevitable.

We know you care about your finned friends and though this process doesn’t seem as tender as one would envision, we assure you it’s completely natural for the Koi. Also, keep in mind rocks underwater are not nearly as abrasive as when above water. They develop a coating of slime called biofilm, and not only is it beneficial to both the pond and fish, but it also makes the rocks quite slick.

Keep the Koi

Kids Safe 

Ok, so now that the deed is done, you may want to partially change the water. After a bout of spawning occurs, the water can get a bit foamy. In about 2 days, the eggs that have been released during spawning- will now hatch. These baby fish, or fry are so small, you won’t really be able to see them. If you have gravel in your pond, this makes a great hiding place for them to hide out, away from danger of being eaten by bigger fish. They will stay there for another day or so, using their yolk sac for energy, then when they are about 24-36 hours old, they will swim up to the foliage of the pond. If you do not have foliage, it’s going to be a short day for a fry. It’s important to remember that most of the eggs, and fry are not going to make it. After all, life’s not easy and nature is a rough and savage place (it’s like Game of Thrones in there). Fish eggs are a favorite snack for not only the adult fish in the pond, but also dragonfly, tadpoles, and frogs.

The fry that do make it, will eat microscopic plants and animals. If you have a pond with a coating of bio-film and a thin greenish layer of algae on things, the fry will have plenty to eat. They do grow fast, as long as they can survive. Some will due to color and cunning and they will live to join the shoal.

Joining the Family 

Baby fish grow about an inch per month in the first year, especially in biologically filtered ponds with an abundant plant life and rich gravel bed to sustain them. When you have a clean, liner bottom, drained pond, expect few fry to live.

Of the babies that do survive, a very small percentage will have any admirable markings or colors. Of course, you’ll love them no matter what they look like, (just like any real mom would) but fish with distinctive beauty is very rare from spawned “homemade” babies in your pond. It’s likely that their coloring will be grey or brown, partly because the genes for that color are extremely common and let’s face it- its good camouflage for growing. Shall we call them “survival colors”? Either way, lower your expectations and leave the collectible Koi to the professional and talented breeders in Japan.

Let’s put it this way, in your pond of a hundred thousand offspring, a thousand will hatch, and a hundred will live to be seen by you. Of that 100, 10 will get big enough to catch with a net and of that 10, maybe one will be tolerable as a “keeper”.

Mixed Company

One thing to keep in mind if you have a pond mixed with Koi and Goldfish, Koi don’t get baby fever. Will they eat a baby fish? More likely yes, but mainly by accident.

Goldfish, on the other hand, are intentional cannibals, especially with big, juicy koi eggs and babies. If you keep your pond mixed; it is almost certain that any surviving babies will be of the goldfish variety, not Koi. So, if you’re hoping for a nursery or school (ok, cheap pun) of baby Koi this Spring, think about relocating your Goldfish to a new neighborhood.   Contact us for more information.

So when your mind starts to wander about the entertainment and joy your pond brings, it’s also wise to think about the general health and care of your pond fish. Healthy fish are crucial for a fun and enjoyable pond experience.

Buy Your Texas Koi Pond Fish from a Responsible Retailer

The first, most important and perhaps the most obvious, overlooked steps in securing a healthy pond fish, starts with purchasing from a responsible retailer. Always ask how long the retailer has had the fish. If they have just received them, ask the retailer to hold the fish for a few days to make sure the fish recovers from stress related to transport and new water chemistry. Never buy sick fish and if possible, quarantine new fish for a few days before adding them to your pond. Not sure what to look for when buying fish for your koi pond? Read our 10 tips for buying fish to help you make the right choices.

Keep a Close Eye on Your Fish

This should be the easiest task at hand, I mean after all isn’t the tranquility of watching your Texas koi fish swim around one of the main reasons you invested in Living the Aquascape Lifestyle™.  It’s best to consult the store or garden center where you purchased the fish, or visit your favorite koi vet’s web page for even more information.

Test Your Water

If you suspect there might be a quality issue, it’s best to test your water.  The level of pH can have adverse  effects on your Texas koi fish if left unaddressed.

If you’re consistently adding beneficial bacteria, have proper pond filtration, and a good balance of fish and plants for the size of your pond, you should rarely have any issues. It’s always wise to keep in mind that outside factors like lawn chemicals can occasionally leach into your pond and cause problems. It’s always best not to apply chemicals to plants or grass near your pond off in order to avoid any contamination.

Understand Water Quality

Speaking of the importance of water, understanding that the majority of issues with Texas Koi Pond Fish are caused by poor water quality. Making sure that the fish population is under control and not over-crowded is the first step in creating a healthy environment.  A general rule of thumb for pond sticking is to ensure you have no more than ten inches of fish (in length) for every 100 gallons of water in your pond. So if your pond is 1000 gallons, you can have a total of 100 inches of fish. You should balance your Texas koi fish population with a variety of pond plants. Your pond plants will help to create a harmonious and natural environment, while absorbing  fish waste as fertilizer and in turn will starve algae of this fertilizer.

In addition, beneficial bacteria should be added to your pond on a regular basis to help keep it balanced. Consider adding the Aquascape Automatic Dosing System, an electronically operated dispenser automatically releases the proper dose of water treatments for your pond.

Feed Texas Koi Pond Fish a High Quality Food

Finally, feeding your Texas koi fish a high quality fish food will not affect water quality and will ensure that your fish are getting all the vitamins and nutrients they need to maintain proper health. Being mindful of how much you feed your fish, as uneaten fish food will decay and can cause an imbalance in pond water. Feed your fish no more than they can eat in five minutes. In the summer, you can feed them up to three times per day. In cooler temperatures, feed them only once – and stop feeding your fish altogether when pond water temperature drops below fifty degrees.

By following these simple tips you’ll enjoy seeing your pond fish swim happily and healthily throughout the pond season! Contact us for more information.
