I found out yesterday that it is ok for me to setup a 5 gallon nano tank on my desk at work. I think I would like to have cichlid(s) i think, but I have never kept them before. I will use the eco complete cichlid substrate, and the tank will be bare other than some cavernous limestone rock. I thought maybe I could have 1-3 individuals in the tank, but they would obviously have to be small species that only grow to a few inches. Can you guys help me out with recommendations. I would like some orange, yellow, and/or blue fish. Do cichlids need a heater, or does room temp satisfy them? Any general tips are always appreciated. I will probably move on setting this up after the holidays.
