The AB Heckelii Cichlid (Acarichthys heckelii), also known as the Threadfin Acara, is a beautiful South American cichlid admired for its elongated dorsal fin filaments and elegant body shape. Mature specimens develop long flowing dorsal rays that give the fish a graceful and distinctive appearance.

This species features a silver to olive body with blue iridescent markings and a dark lateral stripe, making it an attractive centerpiece fish for larger aquariums. Compared to many other cichlids, Heckelii cichlids are relatively peaceful and calm, making them suitable for community aquariums with similarly sized fish.
