Description
Heckel's Threadfin Acara is a beautiful South American cichlid known for its elongated dorsal fin rays and sand-sifting behavior. They are generally peaceful but can become territorial during spawning, requiring a spacious aquarium with fine sand substrate. This species thrives in well-maintained tanks with soft, acidic water and plenty of open swimming space.
