Get them. I would be careful to not mix them with boisterous cichlids as their jaws are not equipoise for fighting. I've lost several after they lost a lip locking battle to other fish. They can be easily damaged.
They are rough on eachtoher. Their conspecific aggression is high so want to start with a group and provide them with plenty of retreats to escape aggression from the more dominant ones. Colors are great and they are pretty mellow to other fish.
There's a sticky Up at the top. I highly recommend you read the full thread.
