Is it time to start feeding the fish? They look hungry. | Decorative Ponds & Water Gardens Q & A

Q: Is it time to start feeding the fish? They look hungry.

Q: Is it time to start feeding the fish? They look hungry.

Ruth – Altoona, PA

A: Talk about feeling hungry! If your fish are actively (or anxiously!) swimming around your water garden, nibbling and tasting your budding plants, and gazing at you forlornly as you eat your peanut butter sandwich pondside, it sounds like your finned pals are ready for some grub after their long winter fast.

Signs like these are telling, but to make sure your fish are ready to start eating regular food again, here are some guidelines to follow.

Take Your Pond’s Temperature

Last fall when water temperatures fell below 40 degrees Fahrenheit on the thermometer, your fishes’ metabolisms slowed way down. For the next few months, they rested in a hibernation-type state when they fasted and lived off the fat stores in their body. They needed no food from you – in fact, feeding them when they’re hibernating can make them very sick.

Now that spring has finally arrived and the sun has warmed your pond’s water to 40 to 50 degrees F, your fishes’ metabolism has kicked back into gear. They’re swimming around and searching for food to fuel their increased activity levels. Begin feeding your fish up to 3 times per week, and only what can be consumed in a 5 minute period. They will need a wheat germ food that’s easy to digest, like The Pond Guy® Spring & Fall Fish Food. Packed with plant-based nutrients, the diet will satiate their hunger, and stimulate growth and fertility.

Pump Up the Protein

Late spring and summer bring even warmer 50 degree-plus water temperatures, and that’s when you can switch your fishes’ diet to one that will help them develop and build some serious bulk. If growing big koi and goldfish is your goal, feed your scaled friends a high-protein diet, like The Pond Guy® Growth & Vibrance Fish Food. It contains 38 percent protein for maximum growth and includes ingredients that will make their colors pop.

If you want to simply maintain their size while supporting their health, offer them The Pond Guy® Staple Fish Food. Perfect for all pond fish, the summer staple diet contains a balanced diet of vitamins, minerals and amino acids. It’s easily digestible and designed for everyday feeding. Plus, it floats – so it makes mealtime fun for you and your fish!

Check the Forecast

Mother Nature has fun with weather – particularly with temperature fluctuations in the spring – so be sure to check the long-term forecast before you start feeding your fish on a regular schedule. Ideally, the weather should be consistently keeping the water a warm 40 to 50 degrees F. At that point, feed slowly to make sure they’re consuming the food at a steady pace and increase the amount as they’re ready.

Happy feeding!

I see unique koi online but I can’t find them at the pet shop. Do they only sell certain ones, or do they change when they get bigger? | Decorative Ponds & Water Gardens Q & A

Q: I see unique koi online but I can’t find them at the pet shop. Do they only sell certain ones, or do they change when they get bigger?

Jeri – Hartsville, SC

A:  It’s easy to spend hours online ogling champion koi. The fishes’ near-perfect silhouettes, vivid color palettes and balanced scale patterns – not to mention their healthy size – inspire hobbyists to go on their own quests for the Holy Grail of pond fish. So they search pet store aquariums. They peruse tanks at their local pond supplier. They even eye their friends’ fishes, finding themselves coveting a golden butterfly or a sparkly gin rin kohaku.

Does this sound familiar?

Unfortunately, championship-quality koi are rare, as are some of the hard-to-find varieties. The good news, however, is that all koi are unique, and each variety has its own distinct color combination, scale pattern and physical characteristics. They’re called “living jewels” for a reason!

Read on to learn more about the different koi varieties – and how to find the exceptional ones.

Colorful, Common Koi

Most pet stores and pond supply shops stock the most popular varieties of koi, including these, below.

  • Kohaku: These fish have a solid white body overlaid with large red markings (hi). Top quality Kohaku display a bright, blemish-free white combined with deep, vibrant red patterns that are evenly distributed along the body.
  • Sanke (Taisho Sanke): These koi look similar to Kohaku, but they also have small black markings (sumi) overlaid on its white base. Experts say a high quality Sanke pattern begins with a great Kohaku pattern, to which the black is a welcome complement.
  • Showa (Showa Sanshoku): Commonly known as Showa, these fish have a solid black body that’s topped with red and white (shiroji) markings. Showa can be confused with Sanke; the difference is that in Showa, the black patterns wrap all the way around the body and appear on the fish’s head. The red, white and black should be evenly balanced, with crisp, clean edges between each color.
  • Ogon: Their metallic scales are in one solid color, typically yellow (Yamabuki Ogon) or white (Platinum Ogon). A clean solid-color head and unblemished body are crucial to a high-quality Ogon.

Exceptional Specimens

If you want to add some rarely seen jewels to your pond, check out these varieties below. Though you may find them at your local retailer, you’ll have better luck sourcing them via online vendors and koi auctions.

  • Shusui: Shusui are the scaleless (doitsu) version of Asagi, which are koi that display a blue net-like pattern on the back that’s complemented by red or orange patterns on the body. In Shusui, the blue net pattern is replaced by a single row of scales along the dorsal line at the top of the back.
  • Kumonryu: Another scaleless variety, Kumonryu have patterns of grey or white combined with black. They will completely change their pattern many times throughout their life. They can go anywhere from solid white to solid black, or any conceivable combination in between.
  • Tancho: Tancho is a popular variation of Kohaku, in which the only red pattern appears as a single red dot on the head. The symmetry and placement of the Tancho mark are main factors in determining the quality of any particular koi.

Whether choosing a common or uncommon variety, look for bright colors, crisp edges and interesting patterns. The koi’s color vibrancy and pattern edges will change over time (dramatically, in the case of the Kumonryu!), but its variety will stay the same; a Kohaku, for instance, won’t change into a Showa.

Nutrients in your koi’s food can affect its color display, so be sure to feed them some Growth & Vibrance Fish Food after transitioning them from their wheatgerm-based Spring & Fall Fish Food. It contains spirulina and stabilized vitamin C for show-stopping color.

Why do koi have barbels? | Decorative Ponds & Water Gardens Q & A

Q: Why do koi have barbels?

Q: Why do koi have barbels?

Janice – Clear Creek, KY

A:  Koi have been growing trendy whiskers way before the hipsters made it cool! Those whiskers—or barbels—are a defining characteristic of the fish. Here’s what they are, what they do, and why the popular pond fish has them.

Super-Sensing Organ
Barbels are sensory organs not unlike whiskers in mammals. Rather than being used for tactile sensing, however, a fish’s barbels are used for taste. Koi, along with catfish, goatfish, hagfish, sturgeon, zebrafish, some species of shark and other carp, have barbels. They use these taste bud-covered organs to search for food in murky water.

Tasting Without Ingesting
Koi and other carp have four barbels, with two on each side of the koi’s mouth (termed “maxillary barbels”). The top two appear shorter than the lower two, but they all serve the same purpose: taste debris without actually ingesting it. Being omnivorous scavengers that forage along murky pond and river bottoms, it’s a good survival skill to have.

Weird Appendages
As spring approaches and you start feeding your finned pals some Spring and Fall Fish Food, take a closer look at these weird appendages. Most koi (except those with mutations) have barbels—even koi fry have them! So go grab a pond net, catch a koi or fingerling, and look closely to see them.

As with hipsters and their whiskers, they probably won’t like you playing with their barbels. But they’re still fun to look at!

We’ve decided to shut down the pond this winter. Do we just need to take out the pump? | Decorative Ponds & Water Gardens Q & A

Q: We’ve decided to shut down the pond this winter. Do we just need to take out the pump?

Tina – DuBois, PA

A:  Oh, if it were only that easy. Even though you plan to shut down the pond for the season, you still need to complete some winterizing chores. Put on your Aqua Gloves and hip waders. Here is your step-by-step guide for closing down shop and storing your pond equipment for the winter.

Step 1: Remove Pond Netting

Do you have a leaf-collecting net covering your pond? Once the colorful foliage has stopped falling, remove the net, shake off the leaves and store it until next fall. If you leave it on the pond, heavy snowfall and ice could collect on it and weigh it down—possibly endangering your fish.

Step 2: Disconnect Filters and Pumps, Lower Water Level

Next, protect your pumps, filters and hardware from the freezing temperatures. Disconnect the plumbing and drain the water from the tubing to prevent them from freezing, expanding and cracking. If your filtration system has built-in ultraviolet filter or if you have a UV clarifier, disconnect it and take it indoors to prevent ice damage. Remove your pump and store it in a bucket of water to keep the seals moist so they don’t dry out and crack. And lower your water level below the opening of skimmers to protect it from expanding and cracking during freezing temperatures.

Step 3: Clean Filters and Media

Natural bacteria that have been thriving in your pond will become dormant and die through the winter, so you can remove your filter media and store it indoors for safe keeping. Be sure to wash the pads or BioBalls with a strong stream of water while they’re still wet; it’s much easier to clean UVs and media when they’re wet versus trying to scrub off dried debris in the spring.

Step 4: Trim Back Aquatic Plants and Remove Excess Debris

Do you have plants in your pond? Tropical varieties—like tropical lilies—must be removed and stored inside if you hope to keep them thriving until spring. Check out this blog post that details how to remove and store them. Hardy varieties can stay in the pond; take some time to trim away dead or dying foliage after the first frost. While you’re at it, pull out your ClearVac pond vacuum and suck up as much detritus as possible. The less rotting debris in the pond, the more available oxygen for fish.

Step 5: Install De-Icer and Aeration
Your fish will take a winter nap through the cold season, but they’ll still need oxygen to survive. If you live in an area that freezes, be sure to install a de-icer, aeration or both (as we feature in our PondAir & Thermo-Pond De-Icer Combo) to help maintain a hole in the ice. That will allow the toxic gases to vent and oxygen to enter while circulating the water.

Step 6: Switch to Wheatgerm Fish Food
If you haven’t already switched to wheatgerm fish food, do so now. Our Spring and Fall Fish Food is easier for your finned pals to digest—which is what they need when temperatures start to fall. As the water reaches 40 to 50 degrees F, slow down and stop feeding them for winter. Remember that with no filtration system running, any waste they produce won’t be sufficiently removed.

Step 7: Add Seasonal Defense
Finally, if temperatures still permit, continue to add natural bacteria designed for cooler temperatures, like Seasonal Defense. The little microbes will continue to break down organic waste that wasn’t easily cleaned from the pond.

As you prepare to shut your pond down for the winter, take time to check off these chores. It’ll make next year’s spring pond season one to look forward to!

Is it OK to continue feeding my fish summer food and just feed them less of it? | Decorative Ponds & Water Gardens Q & A

Q: Is it OK to continue feeding my fish summer food and just feed them less of it?

Q: Is it OK to continue feeding my fish summer food and just feed them less of it?

Don – Livingston, TN

A:  Koi have temperamental digestive systems. To stay healthy and happy, they need specific types of food at different times of year—so no, we don’t recommend feeding your fish summer food as we go into fall. Here’s why.

Feeding Less

Giving your fish less food is a good idea; especially as water temperatures start to drop. This will cause them to produce less waste, which will help in maintaining good water quality, and slow down their digestive systems. Fish naturally do this on their own; they will eat less food as temperatures decrease because the cooler water will slow their metabolism.

Macronutrient Shift

As water temperatures cool, fish need a diet that’s easier for them to digest—a wheat germ-based diet like our Spring and Fall Fish Food—that’s carbohydrate-heavy rather than protein-rich. We recommend using a wheat germ based food when water temperatures are between 40 to 50 degrees Fahrenheit. In the summer, fish crave protein to grow and put on muscle weight. But in the fall and spring, they’re in transition between fasting and feasting and lacking some digestive enzymes, so they’ll need something that’ll gently slow down (or wake up) their metabolism.

Up the Veggies

Even though wheat germ is the most common food to feed fish in the fall, you can still give your finned pals a treat in place of high-protein foods, too. Toss them some Cheerios, oatmeal or brown rice. Share some healthy vegetables, like carrots, pumpkin or frozen peas. They’ll provide important nutrients while being gentle on their system.

50-Degree Mark

As soon as water temperatures consistently read below 40 degrees Fahrenheit on your pond thermometer, remember to stop feeding your fish for the winter. Don’t worry: They won’t starve. The fast will give your fish the opportunity to give its digestive system a break and live off its fat reserves it added in the summer. In the spring, they’ll clean up and look fresher and healthier than ever.

I just saw my favorite koi. He used to have black spots – but where did they go? | Decorative Ponds & Water Gardens Q & A

George – Price, UT

A: Koi aficionados call their fish “living jewels” for a reason. With their rich red, brilliant white, velvety black and shimmering metallic scales, these swimming beauties resemble vibrant precious stones that glisten and glimmer as they glide through the water.

Colorful, Dynamic

Thanks to generations of careful breeding practices, koi hobbyists have developed more than 20 varieties of nishikigoi (brocaded carp) that differ by their scale color and pattern. Some of the stand-out types include:

  • Kohaku: White body topped with large red markings.
  • Sanke (Taisho Sanke): Similar to the Kohaku but with the addition of small black markings called sumi.
  • Showa (Showa Sanke): Black body topped with red (hi) and white (shiroji) markings.
  • Ogon: Metallic scales in one solid color, usually orange, white, silver or gold.

A koi’s color pattern is dynamic through its entire life; the colors and markings change as the fish grows in size and loses and regrows its scales. For instance, a black spot on your Sanke’s back may seem to shrink or disappear beneath its red markings – only to return a year later in a morphed size or shape.

Bring Out the Brilliance

Though it’s part of a koi’s DNA to change its spots, environmental factors can cause modifications as well. Poor water quality, parasites and fungal infections, for example, may fade scale color. Insufficient sun exposure during the winter months, too, may cause colors to wane. But once the water quality is back up to par and sunless sky gives way to bright sunshine, those brilliant colors will return.

On the flip side, some external factors can actually enhance a koi’s color. Fresh vegetables and citrus fruits, like green peas, oranges and grapefruit, can bring out the vibrant red and orange tones, brighten the whites and deepen the blacks. You can also find commercial diets that are packed with ingredients, like vitamin C and spirulina, formulated to boost color.

Summer Color

As warmer weather approaches and your fish start to get hungry again, start them off with an easy-to-digest wheat germ diet, like The Pond Guy Spring & Fall Fish Food, followed by a higher protein, color-enhancing diet, like The Pond Guy Growth & Vibrance Fish Food. Also test your water quality and do what’s necessary to make sure it’s the best it can be. In time, you’ll likely see your koi’s black markings return – or change into something completely different!
