I have never bred fish and am thinking it this would be a fun next step in the hobby for me. I have an empty 55gal and would not be completely averse to picking up a used 75 or maybe 125 (if a good deal could be had). Would love some suggestions for fish (preferably but not necessarily cichlids) I could breed. Ideally these would be fish I could sell (not for a profit) to local keepers or fish stores so no convicts. Any suggestions?
