Parrot fish and fairy fish are not recommended to be mixed together. The specific reasons are as follows:

1. Different personalities: Parrot fish are lively, and their mouths are cheap, so they like to bite other fish. The character of the fairy fish is mild, and it will not attack other fish under normal feeding. If the two are mixed together, the parrot fish will constantly attack the fairy fish.

2. Different body shapes: Parrot fish are too large, and their body length is about 15-25 cm in adulthood. Fairy fish are smaller in size, and their body length is between 12 and 18 cm in adulthood. Although the difference in size between them is not particularly large, parrot fish is more aggressive, so it is not suitable for polyculture. Although some fairy fish can grow to more than 20 cm, they are not common.

3. Different foods: Parrot fish should be fed with colorful feed regularly, while fairy fish prefer some live bait or animal feed, which usually have different foods, so it is not recommended to mix together.

Parrot fish can mix with red devil fish and purple red fire mouth fish, because they are crossed by these two kinds of fish, so it is more appropriate to mix together. In addition to paternal and maternal fish, parrot fish can also be mixed with map fish, Luohan fish, warship fish and silver arowana. These fish and parrot fish are similar in size, and some of them are larger, which can suppress the lively and active character of parrot fish and prevent them from biting fish with cheap mouths.
