So I've sold my 5 red head Tapajos and need some less common interesting South American cichlids to replace them with. Only remaining fish in the tank is 1 7inch red spot severum and 1 5inch heros sp. curare. Tank is 5ft long, sand substrate and lots of drift wood. Filtered with an fx6 and a fluval 406.
Suggestions? I'm feeling really stumped at this point.
