So i know that cichleds are agressive?

They should be okay though when they get full grown (which takes a long time kind of, years) they may start to pick on your other fish. I have 6 pirahannas and about 7 baby chiclids in with them and at one time 2 full grown chiclids in there that I hot from my friend because they were picking on his other fish, not killing them though. So they might pick on your other fish once they are full grown I doubt they will kill them, but maybe your angels I guess it depends on hoe fragile your other fish are.
