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 Airmax® 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.

Is There Anything I Can Do To Keep My Koi Safe From The Heat? | Decorative Ponds & Water Gardens Q & A

Is there anything I can do to keep my koi safe from the heat?

Q: Is there anything I can do to keep my koi safe from the heat?

Shalini – Brinkley, AR

A: Baby, it certainly is hot outside! As the temperatures rise, you might think the coolest place to be is in the pond with your fish. Surprisingly, however, pond fish can feel the heat, too. The warm water feels “stuffy” to them because it contains less oxygen than cooler water. Check out these four tips for keeping your koi and goldfish cool as finned cucumbers.

1. Check your Water Temperature: Ideally, your pond’s water temperature should be at a comfortable 70 degrees Fahrenheit or less. Use the Pond Logic® Floating Pond Thermometer to check the pond’s temp, and if it’s too warm, do a partial water change to give the fish some fresh, cool water.

2. Top Off the Pond: Even if your pond’s water temperature is hovering near that 70 degree zone, it’s a good idea to keep an eye on your pond’s water level and add more when needed. When the mercury rises, remember that your water will evaporate more quickly into the atmosphere.

3. Create Shady Spots: Just as you seek out shady spots to shield yourself from the sun’s rays, fish will do the same to keep themselves cool – and prevent themselves from getting sunburned! Be sure to provide floating plants, water lilies and other types of shade cover for your pond pets. Have fun with it! Add some tropical lilies like the Panama Pacific, tropical bog plants like the Red Canna or other hot-weather plants that prefer the warmer weather.

4. Provide Aeration: Do you like sitting by the fan or swamp cooler during heat waves like this one? Well, an underwater bubbler or aeration system, such as the Airmax® PondAir™ Aeration System, is like a fan to fish. The cooler water that’s loaded with oxygen is easier for the fish to breathe.

While the heat waves persist this summer, follow these tips to ensure your fish stay cool and comfortable in their watery home. They’ll thank you for it!

How Well Do You Know Your Koi? | Decorative Ponds & Water Gardens Q & A

How Well Do You Know Your Koi?

How Well Do You Know Your Koi?

Koi add color and movement to your pond. They’re relaxing to watch. And they’re likely the centerpiece of your water feature. But how much do you really know about your finned friends? Check out these five factoids about koi and impress your fish-keeping pals during your next pond-side shindig.

1. A Long Life Span: Have you heard of Hanako? He’s the fabled koi who lived for 226 years after being supposedly passed down through the generations and was aged by counting rings on his scales. To set the record straight, Hanako has been proven to be an urban myth. Koi typically live 25 to 35 years in a well-maintained fish pond – but that’s still not a bad life span, all things considered!

2. Growth Spurts: Koi, like most other fish, start out as teeny-tiny fingerlings and grow to their genetically determined adult size. But unlike many fish, koi will grow to fit their accommodations – which means they’ll develop into super-sized beasts in the right environment. In their first three to four years of life when housed in an adequately sized pond, a koi will reach about 18 inches long. Throughout its lifetime, it can grow to reach up to 3 feet and more. That’s some big fish!

3. Colorful Gastronomes: The ultimate underwater foodies, koi will eat just about anything, with the exception of meat. Though they love their commercial pelleted diet, like Pond Logic® Growth & Color Fish Food, koi will happily gobble down lettuce, apples, oranges, watermelon, and even tiny shrimp. So why not treat your scaly pals to some healthy fruits and veggies now and then!

4. Feast and Famine: Koi love to eat and will chow whenever food is offered, but these guys can actually go more than 10 days without food during the warmer months – and fast even longer when temperatures drop and they go into their winter torpor, or hibernation, when they pass on meals for months at a time. Of course, if you feed your fish regularly, don’t suddenly stop as doing so can affect their health and happiness.

5. Koi Agility? No, koi unfortunately cannot be trained to jump through hoops like a dolphin or fetch a floating ball like a Labrador, but they can be conditioned to recognize your footsteps and come to the water’s edge for a visit. Simply feed your fish from the same place consistently and, before long, they’ll learn to go there for food and even learn to eat from your hand! Now that’s a cool party trick.

Fish Acclimation In 4 Simple Steps | Decorative Ponds & Water Gardens Q & A

I Overwintered My Fish Indoors This Season. How Should I Go About Placing Them Back Into My Pond? I Overwintered My Fish Indoors This Season. How Should I Go About Placing Them Back Into My Pond?

Tamara – Rapid City, SD

Re-introducing your fish to their summer home can be a safe and simple process if you follow these 4 simple steps:

Perform A Pond Cleanout – Clean your rocks, waterfall, filters and pond equipment. If stuck-on debris are slowing you down, use some Pond Logic® Oxy-Lift™ to speed up the process. Be sure to clean out any bottom-dwelling muck and skim out floating debris. Most people drain their ponds for easier access to the entire pond. If you are not up to the task then perform at least a 20% water change.

Seed & Start Your Filers – Once you refill the pond, replace or clean filter media pads and secondary media like The Pond Guy® BioBalls™. Use Microbe-Lift® PL Gel to introduce beneficial bacteria and reduce filter seed time. Once everything is back in place, start your pumps and let the water flow.

Test The Water – Use a water test kit to ensure pond water is balanced and safe for your fish. A good test kit will include tests for ammonia, nitrite and pH levels as these directly impact the health of your fish. We always recommend adding Water Conditioner or Stress Reducer PLUS to your pond after water changes to detoxify harmful contaminates in well and city water.

Acclimate Your Fish – Water temperature and composition will be different than their winter housing, so it is important to slowly introduce them to their new home. Bring fish out in a bucket and periodically add a small amount of pond water every 5-10 minutes. This will give your fish time to adjust to the water variations and avoid shock. After 15-20 minutes it will be safe to gently release the fish back into their home.

Can I Break A Hole Open In The Ice Over My Pond? | Decorative Ponds & Water Gardens Q & A

Can sidewalk salt be used to melt the ice off my pond?

Can I Break A Hole Open In The Ice Over My Pond?

Liz – Carterville, IL

When maintaining a pond during the winter, it is important that the surface of your pond does not freeze over with ice. If you have an aeration kit running in your pond but the resulting hole in the ice is getting smaller, or has closed up altogether, don’t panic. Sporadic short-term ice coverage is not an issue if you’ve done regular maintenance to reduce organic debris throughout the season. If the pond remains iced-over for weeks at a time, consider giving your aeration system a boost.

If your pond has frozen over and you want to reopen the hole, simply rest a pan of hot water on the surface of your pond to melt the ice away. Do not use a blunt object to break the ice open as the shock-waves will stress your fish. Also, refrain from poking holes in the ice as you may accidentally puncture your liner or poke one of your fish.

Another way to maintain an open ventilation hole is by adding a pond heater/de-icer above your aeration diffuser stone. If you have multiple air stones, gather them into one area to make it more difficult for ice to form.

Pond Talk: Do you notice the ventilation hole getting smaller or freezing over for short period of time in the winter?

What Can I Do To Maintain My Pond This Season? | Decorative Ponds & Water Gardens Q & A

This will be our first full season with our pond. What should we do for proper maintenance?

Joe – Aurora, CO

The first season with your new pond can be an exciting and relatively hassle free endeavor, as long as you take the right precautions to maintain it properly. Lucky for you, you’ve come to the right place to learn exactly what you’ll need in order to successfully maintain your pond for the season.

Remember, a balanced ecosystem is key. Listed below are the main elements used to maintain a balanced pond.

Filtration – Whether you have a waterfall, pressurized or gravity type filter, make sure the included Filter Media is clean and in good condition. Mechanical filtration like skimmer filters should be cleaned regularly to prevent clogging. Biological filter media, like the pads in your waterfall or bio-media in your pressurized filter, should be cleaned sparingly to promote an accumulation of water-filtering beneficial bacteria.

Fish – The highlight of many ponds, fish add color and life to your decorative pond. They also, however, add waste and nutrients that can quickly accumulate and unbalance your pond. 1-inch of fish for every square foot of surface area is a rough guideline for maximum fish load. Keep in mind that your fish are continually growing. That means your 3 inch fish that were added last year are now 4-6 inch fish which more than doubles the waste that needs to be filtered. The more fish you have and the frequency at which you feed them plays a large role in how much filtration you will need to remove this additional waste.

PlantsAquatic Plants are an enormous natural boon to your water garden or fish pond. Not only do they provide habitat for your fish, maintaining 40-60% plant coverage shades your pond and prevents dramatic increases in water temperature on sunny days. Plants also provide additional natural filtration as they extract nutrients from the water added by organic debris and fish waste.

Aeration – Proper aeration is another key factor for pond maintenance. An aeration kit like the Pond Logic® PondAir™ or KoiAir™ will provide extra circulation to keep debris from accumulating at the bottom of the pond while increasing oxygen levels for your fish and water-filtering aerobic bacteria.

Natural Pond Treatments – Natural products like those contained in the Pond Logic® DefensePAC® will greatly increase water quality by boosting aerobic bacteria counts, binding up phosphates from organic material and eliminating organic debris.

Including each of these key pond elements in your water garden or fish pond greatly reduces stress and guesswork associated with a troublesome unbalanced pond. Simply put, a stable ecosystem means less work on your part. If a problem does arise, you can then pinpoint and adjust whichever element above that is throwing your pond out of balance.

We’ve had a mild winter so far, does this affect the dormancy of my fish? | Decorative Ponds & Water Gardens Q & A

We’ve had a mild winter so far, does this affect the dormancy of my fish?

We’ve had a mild winter so far, does this affect the dormancy of my fish? 

Ivy – Schaumburg, IL

We may be having a mild winter, but a mild winter for humans doesn’t really mean the same for your fish. During the winter months, fish living in outdoor ponds will go “dormant,” slowing down all their systems and responses in order to conserve energy during cold temperatures. Monitoring your pond’s temperature is easy – we recommend this handy Pond Logic® Floating Thermometer.

The signs your fish are ready for dormancy are relatively easy to pick out – colder temperatures will mean less food, to which your fish will react to naturally. Their metabolism and digestion will slow down, as will their movement in general, while they conserve energy. Don’t be alarmed if your fish appear “lazy” or don’t have any appetite – this is all normal. It’s also a good idea to wait until spring, or whenever it is consistently warm, to start feeding your fish again regularly. Do remember that your fish will require a couple days to digest their food and even if they become more active on a warm day you won’t want them returning to a dormant state while still digesting.

However, if Old Man Winter does sneak up on you, don’t wait until the first freeze to make sure your fish have enough oxygen and aeration to keep the water from freezing over. We recommend using these Pond Logic® PondAir™ Aeration Systems to keep your pond, and your fish, in good stable condition for the winter.

Some people like to leave their aeration system running year ‘round, so feel free to do so as well, we’re sure your fish won’t mind!
