One of the advantages of cyps compared to other cichlids IMO is the fact that the more males you stock the HAPPIER your colony will be it seems. I will say when my group was 6 males and 1 females the lone female was harassed constantly, but since I expanded it to 12males 4 females it has worked great, so many males that they are showing off to each other and flashing constantly, and enough females so they cant pick on one. Breeding for numbers, each female holds once every 2 months or so.
