? Parrot fish and koi should not be mixed together, because they have different requirements for living environment. Parrot fish is a tropical fish, and the suitable water temperature is 25-30 degrees. Koi is a cold-water fish, and the suitable water temperature is 22-26 degrees. Although their requirements for water temperature overlap, parrot fish prefer a higher water temperature, preferably 28 degrees. Koi prefer a lower temperature, preferably 22 degrees. It is difficult to meet the requirements of two kinds of fish, so polyculture is not recommended.
Moreover, parrot fish are born with defects that make them need more oxygen, and Koi is a fish that can eat and pull, so it needs more oxygen. The two of them are mixed together, and they are easy to lack oxygen. In addition, the best viewing position of Koi is the back, that is, overlooking the most ornamental, so they are generally raised in fish ponds or round tanks. The most ornamental part of parrot fish is its body shape, so it needs to be viewed at the same level, and it is usually kept in the fish tank. If they are mixed together, the ornamental value will be greatly reduced.
? Parrot fish can be mixed with map fish. First of all, they are tropical fish with similar temperature requirements. Secondly, they are all medium-sized fish with similar size. Moreover, the map fish is gentle and slow, and will not attack the parrot. Finally, their best viewing angle is the same, and mixing together can improve the viewing effect.
