I have seen many articles about raising koi in ponds, but I have never seen anything about raising them in ordinary fish tanks. I have six koi, each several inches long, and they currently reside in a 125-gallon tank. The tank has an external canister filter and an undergravel filter. How long is it safe to keep koi under these conditions? Would it be possible to keep them outdoors in a pond but bring them indoors and keep them in the aquarium tank for viewing for several months?

You may have seen the colorful fish at Japanese restaurants or aquariums. Some species of Koi is ideal for home ponds for having as pets or even for food. They are highly resilient and can survive the summer heat and severe winter weathers, even when the pond is frozen. They grow with minimum supervision, and can be a good source of protein or can be used as a major attraction for your backyard garden pond. These selective breeds of German and Asian carp are becoming increasingly popular in backyard garden ponds in America. Although they are colorful and mostly kept for their beauty, they also provide a good source of high nutrition, and the large fish can sell for several hundreds of dollars each.

To keep Koi fish in an aquarium, you want to try to replicate their natural environment, just like you would do with any other fish. Koi fish require very clean fast-moving water, highly-oxygenated water, and they need a very large environment. They get very, very large. Even though freshwater fish, their size will be limited to the size of the aquarium, their growth will be very stunted; their gill plates will keep growing, their fins will keep growing. They’re going to get a hunchback appearance to them. You want to go with a very large aquarium. I don’t recommend Koi for a small aquarium; when I mean small, anything less than 200 gallons. The Koi will just outgrow that, they’re not going to be happy in there.SUBSCRIBE AND LIKE!!.
Today my largest koi decided to spawn in the morning releasing all of its eggs on the Java Fern. I have never ever seen an actual koi spawning live and close up. This is a rare and first for myself especially for large fish spawning in a home aquarium. The largest koi that was spawning was a Sanke.Koi are cold water pond fish, descended from carp. Koi owners may need to bring their prized koi indoors during the winter to prevent death in frozen pond water. Keep koi in large aquariums for a few months at a time. If you live in an apartments, you may have to keep koi in aquariums for their entire life. That is possible, as long as you do not overcrowd the aquarium with too many koi.You will have to decorate the aquarium so that there are suitable breeding areas present for the Koi fish. The materials selected to be used for spawning should be totally submerged and safe to the environment. There are many synthetic Koi breeding materials available in the trade but most professional breeders still prefer the natural ones and think the produce better results. An example of a good natural breeding material is Water hyacinths which are a plant that can be great for building suitable spawning places with. Water hyacints can carry parasites and will have to treated with special substances like Dipterex to eliminate all possible parasites before being used in a Koi breeding setup. Water hyacinths might also attract dragon flies. While these insects are harmless, their larvae can attack and kill the Koi eggs and fry. It is recommendable to use nettings on top of your breeding pond if you breed your Koi outdoors to protect them from predators. It might also be beneficial since they sometimes like to jump and netting prevents them from jumping out of the pond. A benefit that makes the use of nettings on your pond a beneficial choice regardless of whether you keep and breed your Koi indoors or outdoors.
