Can a Koi be kept in fish tank if so will it eat the other fish?

Koi fish can be kept in a fish tank, but there are a few things to keep in mind. First, koi fish grow large and need a lot of space. A single koi fish needs at least 100 gallons of water, and multiple koi fish need even more. Second, koi fish are very active and can easily jump out of a tank. The tank must have a tight-fitting lid. Third, koi fish are omnivores and may eat smaller fish. If you want to keep other fish with koi, make sure they are large enough not to be eaten.

Here are some general tips for keeping koi fish in a fish tank:

* Provide plenty of space. Each koi fish needs at least 100 gallons of water.

* Provide a strong filter. Koi fish produce a lot of waste, so the filter must be able to handle it.

* Provide a lid. Koi fish can easily jump out of a tank, so the tank must have a tight-fitting lid.

* Provide decorations. Koi fish enjoy having decorations in their tank, such as plants and rocks.

* Feed a high-quality diet. Koi fish need a diet high in protein and low in carbohydrates.
