It used to be in my friend's tank, but it started killing everything in his tank so he asked if I wanted it. I've had it for a few months now, but I was always curious exactly what kind of cichlid it was cuz he forgot. I haven't had any problems with it yet. It's shown a little bit of aggression, but it's also the smallest fish in the tank so it doesn't bug my other fish. It's about 8" right now and it's just been eating massivore delite. What else should I feed it? It doesn't touch shrimp, fish fillets, or worms cuz I feed those also to the other fish.
