Thanx. Yes I think she's a severum. Spike who's the cichlid up to the right of the frontosa I think is Copadichromis boadzulu holotype. I looked on the net but not sure. If Princess is a cross convict, that would explain her agression.
I bought the tank 2nd hand and the fish came too. Survived a 2 hour trip and a nearly complete water change. Tough but lovely (so far) that was 2 months back.
Thanks, will try photobucket.
