I have a 90 gal. with 2 parrots 8", and a few small ciclids 2". Would I be able to keep flowerhorns in with them????? I had several larger ciclids, a JD, and 2 oscars in it. I ended up having to remove the oscars. I started missing to many fish. So I put all the larger fish except the parrots in another 90gal. tank. Are flowerhorns agressive???? I was going to get a few small ones. What do you think????
