I'm new to cichlids and i set up a 55gal long tank. My question is how many fish can i safely hold in the tank? I have 10 baseball to softball sized rock caves and a few fake plants in the tank. I've heard many varying fish amount for a tank this size, some being as small as 6 to 8 fish and some as large as 20 fish. I'm keeping a variety of cichlids that are in the 1-2 inch range and reach about 5-6 inch range at adulthood.
