Description
The Heckel's Threadfin Acara is a beautiful South American cichlid known for its distinctive elongated dorsal and anal fin rays, particularly in mature males. While generally peaceful for a cichlid, they can exhibit territorial behavior, especially during breeding. They thrive in well-maintained, soft, and acidic freshwater aquariums.
