You have many fish to pick from. Stick to some of the more easy going SA cichlids. No oscars or temporalis. Other Amazonian earth eaters such as the Juraparoids would work. True Parrots are a good choice too. Remember, species in the surinamensis group need warm (78-80F +) and clean water. Stay away from non Amazoinian species such as Red Humps or GT's.
