Have a pair of Texas male cyano female carpintis in a 125 that are quite prolific. As they are technically hybrid fry they do not leave the premises. The cyano is a real stunner (I am into cyano for whatever reason never really jumped on the carpintis train) and he is the centerpiece of what I would consider a "wet pet" set up. My question is are cichlids best kept in pairs or alone? What are the pro/cons etc. is having a girlfriend good for him?
