Although I don't have them, Pseudotropheus saulosi, Julidochromis dickfeldi, Angelfishes (Koi), German Blue Rams, Apistogramma cacatuoides... What I do/did have (and really like also): Pelvicachromis pulcher & Blood Parrot Cichlid
I really like all small cichlids, less than 6". The exceptions are the Angelfish, Blood Parrots and Discus
