Would kelberi or azul work in a 300 gallon? I plan to have some geophagus and satanoperca mixed in (big eartheater fan) How big are the fish they can swallow? I know ocellaris and monos get quite massive. I have heard Orinos are very slow growers.
Dont keep them hungry. And your going to either like them. Or hate them. The smallest species is kelberi. few kels and azul can be fine. Orino are kinda A-holes imo. but im no expert. Let the real cichla keepers chime in
