I didn’t have fish in my pond before but they are there now. How did they get there? Brenda – Golddust, TN

Where Did YOU Come From?

In states everywhere people are being shocked and amazed by the random appearance of fish in their ponds. These fish were not added by the owners of the pond but there they swim none-the-less, almost mockingly. What is this strange magic?! Is this some form of prank?! Perhaps it is the work of alien beings?! What is going on?

Unfortunately, I can not weave a tail of some sort of intricate conspiracy against pond owners across the nation. The far less captivating reason is that, by some sort of mistake, either you or Mother Nature, have unwittingly moved these fish into their new home. Fish can be introduced into new ponds in quite a few ways. Eggs or fry can be carried in on the feet or mouths of water foul and other animals, or can be clinging onto some aquatic plants you decided to add to your pond. Sometimes flooding can wash fish from nearby ponds, lakes, and streams into your pond. While you can try to prevent any fish from making it into your pond, it is pretty much inevitable that over time, they will find a way to make your pond a place of their own. It is not all bad news though, having a balanced fish population actually contributes to a healthy ecosystem and can actually provide you with a form of entertainment whether it be fishing, feeding, or just watching them from the shore.

Not sure if you have fish? Try baiting a hook and doing a little bit of fishing. Odds are if there are some fish in the pond at least one or two of them will bite. If you are not into the fishing scene you can try to place a Fish Trap in the pond with some bait and see what you pull up. You may get lucky and coax them up to the shore just by throwing some bread or Fish Food into the water. Keeping track of the size, number and types of fish you pull out of the pond will give you an idea of what type of fish population you will be dealing with later on down the road. If you notice you are only pulling out prey fish like Bluegill, you will eventually have an over abundance of little fish swimming around the pond in the seasons to come. To keep things balanced you would want to introduce a few predator fish like Bass to the pond. On the other hand, if you notice that you have a lot of small Bass in the pond, they may need a little more help with finding food. Stocking some Minnows, Bluegill, or feeding them Fish Food will help them grow to a more appealing size. You can read more tips on adding fish by reading our Pond Stocking Blog.

Do fish drink? – Decorative Ponds & Water Gardens Q & A

 Do fish drink?

Do fish drink? Kristie – Doglap, MS

You would think that your koi need a drink of water like the desert needs another grain of sand but just like us; they too need a little refreshment from time to time. Koi utilize water to maintain proper body functions the same as us but they just do it a little bit differently.

Koi don’t per say “drink” like we do. If we want a glass of water, we pour water in a glass and drink away through our mouths. Koi on the other hand absorb water through their gills and body in a process called osmosis. Osmosis is defined by dictionary.com as “the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.“ In other words, koi have larger concentrations of water that contain salt in their body than does the surrounding water garden. Through osmosis water is constantly passing through koi’s semipermeable skin into their body to equalize these concentrations. Since water is constantly absorbing into their bodies they have to immediately excrete this water to prevent them from bursting. During the course of a day, they can excrete up to 10 times their weight.

Feed your fish with the best!

I Just Bought Some New Fish, How Should I Introduce Them To My Pond? – Decorative Ponds & Water Gardens Q & A

Pond Fish & Koi Acclimation
I Just Bought Some New Fish, How Should I Introduce Them To My Pond? Paul – Baytown, TX

Best In Show

So you’ve made the decision to invite a few new friends to your home, but are you getting more than you bargained for? As is true with any purchase, you want to make sure you are getting quality before you hand over your hard-earned dollars. Inspect the fish you intend to purchase for symptoms of illness or poor health. Look over their fins, mouth, and gills for blemishes, discoloration, or signs of fin rot and check their body for growths, loose or missing scales, or other blemishes as they may be an early indicator of disease or parasites. Take a few moments to observe your prospect’s behavior to make sure they are active and having no mobility hindrances.

Prep The Pond

Your newly purchased fish are typically handed over to you in an oxygenated plastic bag or container to allow adequate time to transport them to their new home. While it may be tempting to just dump them into your water garden upon your return home, you will want to make sure your pond is ready to accommodate its new inhabitants before you begin their acclimation process. Here are a few things to keep in mind:

  • Make sure the water in your pond is free from potential fatal heavy metals and chlorine by adding Pond & Fish Conditioner during your water changes.
  • To help prevent disease and reduce fish stress in your new tenants, add Pond Salt to the water between your water changes. To ensure the well being of your Aquatic Plants, only add 1 1/4 cups per 100 gallons of pond water.
  • You can purchase a Master Test Kit to verify acceptable pH and Nitrate levels in the pond.
  • You can prevent many potential health issues throughout your fish population by simply maintaining a clean and healthy pond. You can read more about pond maintenance here.

Well, You Better Get Used To It

Now that the pond is ready for the addition of fish, it is time to get your finned friends ready for the big show. You will want to gradually equalize the temperature of the water your fish are currently occupying with that of the water in your pond. If the container carrying your fish floats, go ahead and place it in your pond. As the bag bobbles around in your pond, the water inside will start balancing with the outside water temperature. This process should take no longer than 30 minutes. During this time frame, slowly add small amounts of water from the pond into the container which will allow your new fish time to acclimate to the chemistry of your pond water. Most of us have, at one time or another, jumped into a pool too early in the summer only to find that the water is unimaginably cold. Those of you who’ve been in that situation understand why you will want to take your time with the acclimation process. Now that the water on both sides of the container is the same and the fish have had time to try out the make up of the water in the pond, you are clear to release them into their new environment! Take a few moments throughout the day to check in on the pond and monitor the behavior of the newly introduced fish. Active and curious fish are happy and healthy fish.

I found what looks like a sore on my koi. What should I do? Could this have happened over winter? – Decorative Ponds & Water Gardens Q & A

Dyed PondQ: I found what looks like a sore on my koi. What should I do? Could this of happened over winter? – Fred in Kentucky

A: As we close in on spring and the ice melts off of our water gardens, our koi start to become lively again. This is a very crucial time for koi. When koi begin to awaken from their winter dormancy, they can show signs of weakness. This is because during the winter, not only do their metabolisms slow down, but also their immune systems can be affected.

As the temperatures outside begin to rise above 40ºF begin a Spring/Summer Prep bacterial application, like Seasonal Defense, and start to feed them Spring and Fall Fish Food. Keep an eye on the koi for any signs of excess slime, sores or lesions. Weakened fish are much more susceptible to bacterial and parasitic infections when the temps are just beginning to rise.

Here are few products to use if your koi happen to be sick:

Using the products mentioned above you can be assured your fish will be lively again in no time. To help prevent koi sickness during the early spring, be proactive and ensure your koi are healthy in the fall time.

How does winter affect my pond? – Ponds & Lakes Q & A

Winter PondQ:  How does winter affect my pond? – Steve in Michigan

A:  A Closer Look at Water in the Winter…

We field many questions about water and the way it works during the winter.  With such a range of questions, here is a quick course on the physical properties of water and how they relate to your pond.

Here’s a review on density.  On our planet, matter that is denser will always be pulled down (gravity) more strongly than matter of lesser density.  Density is temperature dependant in that warmer matter is always less dense than cooler matter.  A good example is a hot air balloon, which lifts up because the air inside the balloon is warmer than the air outside.

A water molecule (H20 – don’t worry that’s as technical as we’ll get) contracts as it gets colder, causing it to become more dense.  As water closes in on the freezing point, we run into one of nature’s great exceptions.  At 39ºF (4ºC) water actually starts becoming less dense as it prepares to shift from a liquid to a solid at the 32ºF mark.  Why is this so important?  This means that water at the bottom of your pond will always stay about 39ºF because it is the heaviest.  We refer to this as inverse stratification, where a pond has a thermocline that separates warmer water on the bottom from cooler water on top (FYI, normal stratification occurs during the warmer months of the year when the cooler water is at the bottom and the warmer water is at the top).

Winter PondHow does this apply to your fish?  Fish actually get quite sensitive to temperatures below 39ºF.  This warmer 39ºF pocket on the bottom of the pond is where they tend to hang out during the winter.  This is why it is recommended that an aeration system be installed a couple feet up from the bottom of the pond to keep the 39ºF water in tact. Should you worry if yours isn’t? No, not really, mortality due to water temperature is extremely rare and NOT aerating is way more risky. The more severe issue is the toxic gases under the ice. Continuing to aerate will vent these gasses while also infusing oxygen into the water keep your fish happy and healthy.

Why Are My Fish Hiding? – Water Garden & Feature Q & A

Why Are My Fish Hiding?

Water Gardens & Features Q & A

Q: Why are my fish hiding now when they didn’t before? Is something wrong with them? – Rob in California

A: There’s nothing more frustrating than hiding or skittish fish. Part of the joy of having a water garden is to sit by the pond’s edge, feed your fish and relax while you watch them enjoy their underwater world. When they dash off and hide at the site of anything coming near them, or they hole up and never come out, it almost defeats the purpose of having koi or goldfish in your pond! Here are a few reasons why your fish may be hiding.

New Digs

It’s tough to move into a new pond. If you’ve recently added new koi or goldfish to your water garden, you can expect them to be a bit shy or skittish. They need to check out their new home, get used to having new roommates and adjust to a new way of life. The fish already living in the pond could turn tail and hide, too. The new fish could spook the old fish, causing them to retreat to their favorite hole.

If this is the case in your pond, give the fish time to adjust. As soon as they’re used to their new home and used to one another, they’ll eventually come out of hiding. Encourage them to be social by tossing some floating food, like Pond Logic® Floating Ponstix Fish Food, into the pond. That’ll bring them to the surface!

A word of advice: Before adding new fish to your pond, remember to quarantine them for a week or two in a separate tub to be sure they don’t have any parasites or fungal infections that could infect the rest of your population.

Water Changes

Fish can also become skittish and hide after water changes. Any change to their environment – like the water quality, pH level, or oxygen level – can cause them to stress, and when they stress, they may retreat to their favorite hiding spots.

To keep the water quality as even as possible, test your water’s pH, ammonia, nitrite and phosphate levels regularly using a commercial water testing kit. You’ll also want to keep your water well-aerated using a diffuser, like the Water Garden Professional Aeration Kit, to be sure the fish get an ample supply of oxygen. Also, be sure to check your filtration system regularly, cleaning or replacing filter media as needed.

Predators

Imagine looking up and seeing a clawed paw grab for you or a sharp beak slice through the water. Predators, like raccoons and herons, love a good sushi dinner – and that’s how they see your fish! If your pond and its inhabitants have been visited by hungry predators, your fish are hiding for their lives.

To chase off unwanted visitors, you can try a range of deterrents, including motion-activated sprinklers, like the Motion Activated Scarecrow; decoys, like the Great Blue Heron Decoy or 3-D Coyote Decoy; pond netting, like the Atlantic™ Pond Protector Net Kit; or reflective tape hanging from trees. Having 40-60% surface coverage of aquatic plants such as water lilies, water hyacinth or water lettuce will give your fish a place to shelter themselves from predators.

Under the Weather

Stressed or sick fish will also hide. If they’re not feeling well, it’s normal for them to segregate themselves away from the crowds. If you think your fish may be sick, try taking a closer look at it. Using a net, like the 3 in 1 Interchangeable Pond Tool, fish it out and put it in your quarantine tank. After you determine what the problem is, treat the fish and the pond accordingly.

Do I Have to Take My Koi Out of My Water Garden for Winter? – Water Garden Q & A

Picture of a Water Garden in the Winter with a Bubbler Aeration System.



Q: Do I have to take my koi and goldfish out of my water garden for the winter? – Barbara of Massachusetts

A: No you don’t actually. They are many water garden owners who leave their koi and goldfish in their water garden throughout the winter season with no issues whatsoever. There are really only two things that you need to do to make sure your water garden is fit to allow fish to winter over:

Does your water garden have a depth of at least 18″?:
This is very important. There are places in the US alone where water freezing depths can easily be around 18″ to 24″. I suggest a minimum of 18″ of depth to be safe, but I am more inclined to recommend 24″ just to be double safe. We want to make sure our fish friends don’t become icicles. In either instance, it’s also extremely important to make sure we keep a hole open in the ice during these cold times, which leads me to the second thing.

Keeping an open hole in the ice during the winter:
During the winter, when the ice forms a solid layer across on the surface of your water garden, there are toxic gases, caused by decaying vegetation or organics, that can build up underneath the ice. This build up can become so toxic underneath the ice that it can kill all of the fish in the water garden. The best thing to do in this situation is to keep a hole open in the ice to allow for these gases to escape. This is actually very easy to accomplish. Using a pond heater/de-icer, such as a Pond Saucer or ThermoPond, is a great way to keep a hole open in the ice. Another way to keep a hole open in the ice would be to use a small bubbler aerator. These will not only keep a hole open in the ice, but will also add oxygen as well! Bubbler aerators can be used all year to keep oxygen levels high.
