I hope the 55g stock in your signature is not the community to which you want to add dwarf cichlids

Looks like it's probably an old list but just checking.
I see you had rams before, how did you like them? Did they breed & live 5+ years for you? Rams tend to be a bit overbred & a little more delicate than my experience with cacs. But they sure are pretty!
Might be time for a change, try something new. I like the apisto's very different male & female appearance but not the old male "hump head" look after a few years. Mine were locally bred & I think that helped with their "sturdiness". The cac males also grew bigger than males rams...or maybe my rams didn't live long enough. I was a much better fish keeper with different water for the apistos, better for both I'm betting.
Are you pretty good about weekly water changes? Water quality, good stock & good foods in that order are important. I'd quarantine them for 4 weeks if possible.
& just to be evil, lol...a 55g is big enough to have a pair of each depending on what else you have with them & décor/tank layout. Each pair will need half the bottom of the tank without more than a bottom feeder or so. Just something to think about...not a "breeding set up" although a fry or 2 might survive if you're lucky.
Bottom line get what you like!
