My Parrot fights the Salvini and Red terror often for control of the tank.So for him, he is not as peaceful as the smaller one I have. The other parrot I have is very docile. Perhaps because he is a lower rank.But mine are all cichlids. You have nice fish in your tank.
They can grow big, and they are cichlids. So you might get one that is aggresive. Hopefully someone else has actually kept them with non cichlids and can share with you what they know.
No way do you put the labs in there Mono with the other fish she has.
