Now that water temperatures are warmer, what should I feed my fish? | Decorative Ponds & Water Gardens Q & A

Q: Now that water temperatures are warmer, what should I feed my fish?

Q: Now that water temperatures are warmer, what should I feed my fish?

Martha – Clifton Forge, VA

A: After their long winter nap, just imagine how ravenous your pond fish must be! Now that water temperatures have climbed to a relatively toasty 55 degrees Fahrenheit, your koi and goldfish are wide awake and ready for some serious grub packed with muscle-building protein and energizing carbohydrates and fats.

When choosing a food for your finned pals, you have several options:

FOR GOOD OVERALL NUTRITION …

Looking for an all-purpose pond food? Check out Pond Logic® Ponstix and TetraPond® Pond Sticks. They’re nutritionally dense and well-balanced fish diets that contain digestive enzymes and amino acids for optimal fish health. Both are economical choices to feed to your fish every day.

FOR VIVID COLOR ENHANCEMENT …

Do you want your koi’s rich reds, pearly whites and deep blacks to shine? Pond Logic® Growth & Color, TetraPond® Koi Vibrance® and CrystalClear® Koi Food are enhanced with vitamins, natural color intensifiers and chelated minerals to transform your koi into the most colorful swimming jewels they can be.

FOR THE SMALL FRY …

Spring brings spawning, which is something your koi and goldfish might be doing right about now—especially with the nutritious food you’re feeding them. Though the little guys will gobble algae and underwater plants when they’re very young, they’ll quickly graduate to fish food like CrystalClear® Goldfish Mini Pellets by summertime, so be sure to have some handy.

In the meantime, make sure the fry have safe spots to hide while they grow, like a Spawning Incubator. Made with polyester fur and fine mesh, the incubator protects them from being consumed or lost in your filtration system.

Is it normal for my koi to change color? Why does it happen? | Decorative Ponds & Water Gardens Q & A

Is it normal for my koi to change color? Why does it happen?

Q: Is it normal for my koi to change color? Why does it happen?

Judy – Southport, NC

A: They say a tiger can’t change its stripes – but did you know a koi can change its colors?

As you get to know each one of your koi personally (and you will if you haven’t already!), you may notice changes in the pigment, color depth and hue in the fish’s black, white and red scales. Don’t worry: It’s not necessarily a cause for panic. The color changes can be caused by several factors, including:

Sun Exposure: During the summer when the sun is shining, you get a tan; during the winter, you don’t. It’s the same thing with koi. Their scales can change color depending on their exposure to that bright orb in the sky. They won’t turn an Oompa-Loompa orange during the summer (though that may not be a bad thing to some koi keepers!), but you may notice a color change in some of your fish after their winter slumber.

Genetics: Koi experts will tell you how critical a role genetics plays in the coloration and patterning of koi. Dominant and recessive genes dictate how much hi (red), sumi (black), shiroji (white) and other colored markings appear. And, just like your hair color can change based on your genetic makeup, the koi’s scale color can change, too.

Stress: If your fish are stressed, they may show their unhealthiness in their coloring – just like when you take on a pallor-type tone when you’re under the weather. Make sure to keep your pond clean and well-oxygenated with an aeration system, like the Pond Logic® KoiAir™ Water Garden Aeration System. Also be sure to check your water quality with a water test kit, like the PondCare® Master Liquid Test Kit that measures ammonia and pH, and correct it if necessary.

Diet: A koi’s overall health – just like human’s – is affected by what it eats. Feed your fish food that has enough vitamins and nutrients to support vibrant color, like Pond Logic’s Growth and Color Fish Food. It contains top-quality ingredients, vitamins, natural color intensifiers and chelated minerals that enhance colors in koi and goldfish. To punch up your koi’s colors even more, add some oranges and watermelon to its diet.

I Know That Floating Plants Help Shade My Pond, But What Do Submerged Plants Do? | Decorative Ponds & Water Gardens Q & A

I know that floating plants help shade my pond, but what do submerged plants do?

Q: I know that floating plants help shade my pond, but what do submerged plants do?

Donnita – Palos Park, IL

A: Got plants? If you’re like most pond hobbyists, you probably have plenty of growing and blooming greenery surrounding your water garden – but what about sub-surface varieties? Underwater plants, like hornwort, and red stemmed parrots feather, offer great benefits to your water feature and its inhabitants, including:

Filtration: Underwater plants naturally filter your water. How? Plants, with their copious amounts of surface area on their leaves, stems and roots, absorb nitrates and fish waste – which is actually fertilizer to them. The result is a body of water that’s cleaner and clearer, thanks to Mother Nature’s nitrogen cycle.

Predator Protection: Sub-surface plants also give your fish and other pond critters places to hide when predators stalk or attack. Koi and goldfish will swim into the lush growth and hide out when a raccoon stops by the pond or a blue heron circles overhead. The greenery provides excellent camouflage for your finned friends.

Aesthetic Appeal: As popular as they may be, gravel-bottom ponds are boring. And they’re not very natural-looking either. Have you ever seen a wild pond or lake with no plants beneath the surface? Nope, didn’t think so. Ponds planted with below-the-waterline foliage create a more realistic-looking – and aesthetically pleasing – water feature, which is something most (if not all!) hobbyists hope to achieve.

Oxygen: Underwater plants are called “oxygenators” for a reason. They naturally produce oxygen as a byproduct of photosynthesis – and oxygen is one of the best things for your pond’s health and vitality. When submerged plants are used in combination with a sub-surface aeration system, you’ll wind up with cleaner water that truly supports your pond’s inhabitants.

Spawning Areas: The leaves, stems and root systems of underwater plants give your pond life safe places to spawn and lay their eggs. And when those tiny fry hatch, the plants provide protection, food and a comfy place to call home.

Submerged plants are easy to add to your water garden or fish pond. Simply fill planting baskets, like the Laguna Submersible Pond Planting Baskets, with planting media, add some oxygenators, and place the planted basket on the bottom of your pond or on a plant shelf on the side of your pond. The planting baskets allow the plant’s roots to branch out and find nourishment while containing it and preventing fish from nibbling on its root system.

Add some plants to your pond today. Your fish will thank you for them!

How Many Fish Should I Put In My Pond? | Decorative Ponds & Water Gardens Q & A

How many fish should I put in my pond?

Q: How many fish should I put in my pond?

Grady – Nevis, MN

A: The general rule for stocking your pond is 1” of fish for every one square foot of surface area, but of course there are exceptions to every rule. First and foremost, don’t forget to leave room for your pond fish to grow. Stocking your pond with 10 one-inch fish may be fine for now, but what about next year when your pond fish have doubled or tripled in size?

Additionally, larger pond fish produce exponentially more waste than smaller fish so you need to factor this into your plans. Look at the chart below for an example of what I mean. One 6” fish produces 3.3 times more waste than one 4” fish and 26 times more waste than one 2” fish. In general, it’s probably best not to stock your pond to the max right away. As your pond is more established and you add better aeration and filtration, your pond will be able to handle more fish.

There are a variety of koi fish packages to choose from when you are ready to get started.

Fish Length Fish Waste (Grams/24 Hours)
1″ .10
2″ .75
3″ 2.43

5 Tips For Feeding Your Fish | Decorative Ponds & Water Gardens Q & A

Is There A Special Way I Should Be Feeding My Fish?

Robert – Santee, SC

Start Feeding Pond Fish When The Weather Warms - Once your pond temperature reaches to 45 degrees, fish feeding can begin. During the colder months, your fish are hibernating live off of their stored body fat.

Train Your Fish - Fish need a schedule. Feed them in the same area at roughly the same time each day. Eventually, they will show you that they are ready for food by rushing to greet you at the edge of the pond with their mouths open.

Feed Pond Fish Slowly - At first, add only one or two pellets to the pond. This causes a ripple on the pond surface that will get the fish’s attention. Once the fish begin coming up for food, you can increase the amount of food given.

Don’t Over-Feed Your Fish - New fish may only be able to eat a small amount. Once they become more alert and accustomed to being fed, they may start to eat a little more. Don’t offer any more food than what your fish can eat in about five minutes.

Use The Right Food - This one depends on what kind of fish you have. Some of the most popular pond fish for backyard water gardens are Goldfish and Koi. We recommend feeding these fish either Pond Logic® Growth & Color or Tetra Pond™ Koi Vibrance.

Most water gardens I see are kidney shaped, is there a reason for this? | Decorative Pond & Water Garden Q&A

Most water gardens I see are kidney shaped, is there a reason for this?

Most water gardens I see are kidney shaped, is there a reason for this?

Frank – Queens, NY

Just as variety spices up life, interesting shapes give a boost to the appeal of any backyard water garden. Because the kidney shape curves conveniently to form a perfect vantage point – where the entire pond is visible – it’s especially popular. It’s also a simple feature to install, starting with our custom cut Firestone 45 Mil Pond Liner. Using this 45 mil EDPM liner and some careful preparation, you can have your own custom-shaped water feature up and running in no time.

During your planning and preparation, you’ll want to consider the kidney shape, which allows much more than a convenient point to view your water garden. It also adds a touch of style without sacrificing function – while keeping the pond healthy by ensuring a generalized flow of moving water. That flow, of course, is best achieved by the use of pumps, skimmers and filters, which draw water from one end of the water feature to the other.

For maximum circulation – an immediate boost of visual interest – we strongly recommend the installation of a waterfall at one end of your water feature, with a skimmer and pump at the other. With the use of our Atlantic Pro Waterfall Filter Falls Box, your waterfall with double as an efficient filter designed to establish and maintain a balanced ecosystem for both fish and plants alike.

How do fish go dormant? Are they really asleep? – Decorative Water Gardens Q & A

How do fish go dormant? Are they really asleep?

How do fish go dormant? Are they
really asleep?

Ryan – Falston, MD

With the warm days of summer now a distant memory and fall following in its footsteps your Koi are left with a few months of cold weather with nothing to do but relax. Since they don’t have miniature submerged Koi calendars to check what is it that tells your fish it is time to hibernate?

Koi are cold blooded creatures which means their body temperatures and activity levels are directly correlated with the ambient temperature. Koi are active and alert when their environment is warm and will start to slow down as the water temperature decreases. Once the water temperatures start to dip below 46°F your fish tend to stop eating and will retreat to the bottom of the pond. Your fish use the decrease in temperature along with the shortening day lengths as a trigger to prepare for winter. As the water begins to cool your fish will become less active as their bodily functions slow down. Less activity means a slower digestive process, less demand for food. It is this decrease in food digestion that warrants the use of wheat germ based foods like Pond Logic Spring & Fall Fish Food. These types of food are easier to digest that regular food reducing the risk of leaving undigested food to rot inside a dormant fish which can potentially be fatal.

As the temperatures continue to decline towards 40°F, the blood flow and respiratory rate of the fish will drop to an extremely low rate where their body is hardly functioning. You may hear people say that your Koi are sleeping in the winter and while fish do sleep this goes way beyond the standard drop in bodily functions associated with some much needed shut-eye. This extreme internal slow down ensure survival with even the most limited resources with cases of dormant fish lasting 150 days without food.

The whole over-wintering scenario sounds a little extreme to us but it is truly a natural and normal process for your fish. They do not require much attention in the winter but there are a few things you can do to ensure their winter break is a success. When a layer of ice begins to form over the pond, maintain an opening for gas exchange using your aerator or a de-icer. Also, make sure you feed with a cold weather formulated fish food as water temperatures approach 50° so your fish are able to safely digest it before hibernation begins. You can use a pond thermometer to keep track of the water temperature in your water garden.

Can Koi and Goldfish Breed? – Decorative Ponds & Water Gardens Q & A

Can Koi and Goldfish Breed?

Can Koi and Goldfish Breed? Sheldon – Huntington, KY

Would That Make It A Koldfish?

Your fish have finally spawned and after what seems like eons of waiting they are starting to grow into full grown Koi…or Goldfish…or…what are they? Your newcomers seem to have unique new patterns and colors that are difference than their alleged parents, is it possible your Koi and Goldfish have crossbred?

While it is possible to crossbreed the two types of fish, it is fairly uncommon for the process to naturally occur in your pond. The outcome of such instances yields sterile offspring that are unable to reproduce. It is much more common to produce new colors and varieties of fish due to two different types of goldfish reproducing. While some pond owners are curious about the potential to crossbreed their fish, many more would be happy to just experience the spawning process even once in their back yard water garden regardless of the results. If it has not happened for you yet, make sure you are providing adequate habitat in the form of submerged plants so if your Koi do spawn the eggs and fry will have places to attach and hide to avoid becoming an easy meal (yes Koi will eat their own young). Furthermore, maintain a healthy water feature by providing adequate filtration, aeration, and beneficial bacteria. Using the products in a Pond Logic DefensePAC will give you a wide assortment of products that simplify your pond maintenance and promote a clean healthy environment.

Why do I need to test for carbonate hardness in my lake or pond? – Pond & Lake Q & A

Testing for Carbonate Hardness

Pond & Lake Q & A

Q: Why do I need to test for carbonate hardness in my lake or pond? – Jose in Michigan

A: A number of pond treatments, including some algae-control formulas and other herbicides, contain copper. In certain conditions, the copper chelate may break down and release copper ions, which could cause your pond or lake’s alkalinity to rise.

If you use these treatments in a pond or lake stocked with trout, koi or goldfish that are sensitive to high alkalinity levels, you need to test your hardness regularly to ensure the health of your fish population.

What is Carbonate Hardness?

Carbonate hardness, or alkalinity, is the measure of carbonate and bicarbonate concentrations in your pond or lake’s water. Alkalinity is a measure of the ability of a solution to neutralize acid without changing the pH. It both controls and maintains water pH.

Alkalinity is related to the amount of dissolved calcium, magnesium and other compounds in the water, so alkalinity tends to be higher in harder water. It naturally decreases over time through bacterial action that produces acidic compounds that combine with and reduce the alkalinity components.

In a pond or lake, the alkalinity of the water is critical to the health of the fish – especially for trout, koi and goldfish. For these fish, the carbonate hardness of your pond or lake must exceed 50 ppm for the fish to survive, ideally falling between 50 ppm and 200 ppm.

Testing 1, 2, 3

When you’re treating your pond with a product like Pond Logic Algae Defense, be sure to use a water hardness test kit, like Laguna Quick Dip Multi-Test Strips.

Carbonate hardness is measured in degrees (KH) or in parts per million (ppm). Because the water hardness test kit will give its results in degrees, you’ll need to convert your findings from KH to ppm to determine whether the levels in your lake are safe for your fish. Use this formula to figure it out: 1 KH = 17.848 ppm. So if your test kit reads 5 KH, you would multiply 5 times 17.848, which equals 89.24 ppm.

Why are my goldfish changing colors? – Water Garden & Feature Q & A

Why are my goldfish changing color?

Water Gardens & Features Q & A

Q: Why are my goldfish changing colors? – Emily in New York

A: Whether you have a traditional goldfish in your pond or one of the many fancy varieties, you may notice their colors change over time – don’t worry. It doesn’t necessarily mean your fish have some sort of disease! In most cases, it’s normal for goldfish to change color. So before you start dumping antibiotics in your pond, first consider these possibilities:

Genetics

Goldfish naturally change color as they age. Though most do so during their first year or two of life, others change throughout their lifetime. Fish experts have identified two different types of color changes in fish: physiological and morphological.

Physiological changes occur when the pigments in the cells either spread out, which makes the colors more pronounced, or when the pigment clusters in the center, which makes the colors more muted. Morphological changes occur when the actual number of pigments in the cells increase or decrease. An example of a morphological change is when a black goldfish starts to turn orange or a young goldfish loses its black markings as it ages. In this case, as the fish matures, it’s losing its black pigment cells.

How and when their colors change really depends upon their individual genetic makeup. Inexpensive goldfish whose parents are unknown can change in unpredictable ways, while expensive show-quality fish will be a bit more predictable.

Color-Enhancing Foods

Certain types of food, like Pond Logic Growth & Color Fish Food, can accentuate subdued colors in goldfish, too. Sometimes, a dull orange goldfish can be made a deeper shade of red with these specially formulated diets, which contain natural color-enhancing supplements like spirulina, beta glucan, vitamin E and vitamin C.

Keep in mind, however, that some of these color-enhancers may affect other colors, too. White areas on calico orandas, for instance, may take on an orange hue – which may not be the look you’re going for.

Illness, Poor Water Quality

If your goldfish’s color becomes very dull or it starts to become inactive, that could be a sign of illness or poor water quality. Use a test kit, like the Pond Care Master Test Kit, to check your water quality, including your pH, ammonia and nitrite levels. Then, if necessary, add a broad-spectrum medication, like Pond Care’s MelaFix or PimaFix, to treat parasites or bacterial infections your fish may have.
