Koi Fish Care In Aquariums. The rule goes a koi pond should hold 500 to 1000 gallons of water for every adult koi it carries. To keep koi fish away from your aquatic and decorative plants it is a good idea to add weed and algae in your tank so they can eat those instead.
Keep koi in large aquariums for a few months at a time. Yes Koi can live in very cold water outside but these are not outside fish now however some hobbyists might argue that a chiller would even be better to have on the aquarium set up. A healthy Koi diet needs to include some fish including crabs sea turtles fish squid shrimp and crustaceans.
Young koi can be kept indoors in an aquarium of at least 29 gallons.
It is best to feed your koi fish 3 times a day because they will continue to eat whatever is available in the tank anyway. Many people opt to raise young koi fish in indoor aquariums then release them into ponds once they reach a certain size. But all of them are hardy temperature water fish that can be kept in both outdoor ponds and indoor aquariums. What Other Fishes Can live.
