I used to call the angel fish a swallow fish, which is a quiet fish. The fish of the family Lampidae is too small. After all, the fish in the family Cyprinidae are not big. The swallow fish likes to bite fish in order to be quiet, so it is not suitable to keep peacocks with small fish of the family Lampidae. The swallowfish will bite the tail of the guppy. If you want to raise it in a mixed culture, because the swallowfish is a medium-sized cichlid, it is best to choose the cichlid family, which includes the blue Arowana, the yellow Arowana, this Arowana, and the Lili fish. The reason is that these two kinds of fish like to swim underwater. Swallows are used to swimming in the middle, so they are the first choice. Because there are many large fish in the cichlid family, the only ones I can think of are the two I mentioned above, and then there are There are many species of swallows, such as panda swallows, black and white swallows, zebra swallows, diamond swallows, red-eyed diamond swallows, which are the best types of swallow fish. The water temperature requirement is about 22-25, which does not require much water quality. Then there are black swallows. The two types of glass swallows are relatively more difficult to clean than the previous two. The water quality requirements are about 22-28 degrees. If the fish tank is large, it is recommended to choose several varieties of swallows and put a few mangos. Dragon or Lili, but I think Lili fish is better. The water temperature requirements, habits, etc. are basically the same as the swallow fish.... I hope what I said will be helpful to you
