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.

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 and replenish the protective slime coating of your fish by adding Stress Reducer PLUS 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.

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.

Now that the rain and warmer weather has melted the ice away from your water garden you can see your decorative pond fish moving about the pond. After a long winters rest you would think they are hungry and ready to eat but it may still be too soon to feed your fish.

Temperature is a major determining factor in whether or not it is time to feed your fish and what type of food you should feed them. Install a floating pond thermometer within reach of the pond’s edge so you can readily check water temperatures throughout the day. Once the weather warms up enough to keep the pond water continually over 40°F you can start feeding your fish a wheat-germ based food like Pond Logic® Spring & Fall Fish Food. As your fish are still a bit chilly their digestive tracks are working at a decreased rate. Foods designed for cooler weather consist of easy-to-digest ingredients that can be broken down faster so they don’t sit inside your fish and cause problems.

Once water temperatures rise above 50°F you can switch over to your growth and color enhancing foods like Pond Logic® Growth & Color or Pond Logic® Professional fish foods. As your fish will be warm and fully active, they will have no trouble breaking down these denser high-protein foods.

Your decorative pond fish will naturally want to eat at any chance they get whether they are hungry or not. They commonly fool their owners into thinking they are starving as they splash around at the surface of the pond and fight for every last pellet you throw to them. Be sure to wait for the temperatures to rise before you give them food and rest assured that a small handful of food each day is all they need to maintain healthy diet.

When it comes to backyard ponds you may hear multiple names thrown out like water garden, Koi pond, decorative pond or other, more creative, titles. While these names are used loosely and interchangeably by many-a-pond owner there are considerable differences between a water garden and a Koi pond used for spawning and raising Koi.

So what draws the line in the sand between Koi ponds and water gardens? Water gardens are geared more towards the every-day pond owner as they are tailored to be easier to construct and maintain while having a higher aesthetic appeal and yard friendly design. Decorated with spitters, plants, lighting and other outdoor décor, water gardens can contain can contain all types of fish with goldfish and Koi being the most popular. Koi ponds tend to be sought after by pond owners that plan raising an abundance of Koi for selling or showing in fish clubs or competitions. With this goal in mind these ponds discourage the presence of species like goldfish as they breed prolifically and take up valuable space for their prize winning koi.

Another distinguishing factor is the design of the pond itself. Water gardens are typically less than 2 ft. in depth and contain plant shelves around the outside perimeter to hold a wide variety of aquatic habitat and visual stimulation. While a koi pond may also include plants for filtration or aesthetic appeal the design of this type of pond is all about the koi. These ponds do not contain plant shelves and are usually 4 ft. in depth or more. One reason for this is to discourage predators and increase useable area for their fish to roam and grow. Koi ponds also utilize bottom drains and large amounts of water flow to create ideal breeding conditions. As Koi breeders want to fit as many fish as they can into their ponds they rely on complex heavy duty filtration systems, and UV sterilizers to keep pond water clean. These systems are much more complex then the pond skimmers, pressurized filters and waterfall boxes water gardeners use.

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.

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.

Koi FeedingQ: How do I know when I can feed my koi again? – Jim in Michigan

A: Now that we’re at winter’s peak, many of us begin to think about the coming spring.  As we start the spring to-do list, we remember those poor little koi that are out in the water garden.  Since you’ve kept a hole open in the ice all winter, you really have nothing to worry about, right? But your koi seem to be a little more active lately with the approaching spring and look like they have a mighty appetite since they haven’t eaten all winter. Should you start feeding now, or later? This all comes down to water temperature. Let me explain.

During the winter months koi go into a state of near-hibernation where their bodily systems are doing just enough to keep them alive.  Much like the frogs and turtles, koi typically do not eat during this time.  This is because their digestive tracts have slowed down so much that food cannot be fully digested by their stomachs. It is for this reason that we recommend that you stop feeding your koi altogether once water temperatures dip down below 40ºF.  As water temperatures being to climb between 40ºF & 55ºF the optimum food to feed your koi is a wheat germ based fish food like Spring & Fall Fish Food.  Wheat germ is specifically designed to be easy on the digestive tract for koi as they transition in and out of winter.

Fish FoodSo in summary, during the spring thaw watch your water temperatures. As they approach 40ºF, you will notice the koi becoming more active. At this point, throw in a very small amount of Spring & Fall Fish Food to see if they are interested. Once they start eating the pellets, you can begin ramping up the spring feeding. As the koi eat, continue to increase their rations (never more than they can clean up in a few minutes) until the water temperatures reach their normal levels for the summer. At this point, switch them over to a higher protein fish food like Growth & Color or Professional Fish Food.
