Ok, so I got a new 55g tank Monday, and the guy gave me 6 Cobalt Cichlids, I believe they are all males, and I don't know what to do with them. I know I want to keep them, but I don't know anything about them. What do they eat? What water do they like? What other cichlids do they get along with? They are in the 55 with a divider, but all thats in the tank is gravel. Does anyone have any advice on them?
