I have been keeping cichlids for about 2 years and I'm thinking about putting discus in my 29g. I read the sticky on this forum (I am in the research stage of the plan) and there were a few things that worried me. My biggest fear is that it says they should be kept in groups of at least 4 and each discus needs 10 gallons. Does this mean my 29g tank is too small? As I could either get 3 of them or crowd them. Could this work? Thanks for your help!
