I have two aquariums that house dwarf cichlids. My 72 gallon has a pair of Kribs and Red Rams. My 90 gallon houses a pair of Gold Rams and a pair of Cockatoo Dwarfs. I have been doing some research on these fish and have read that they will spawn easier in groups and generally do much better when there are 3-4 of them. Does anyone know if this is correct? I have had these pairs for a few months now and they seem happy. If anyone has any advice please let me know.
