Description
The Threadfin Acara is a beautiful South American cichlid recognized by its elongated dorsal and anal fin rays, giving it a distinctive 'threadfin' appearance. They are generally peaceful for a cichlid but can become territorial, especially when breeding or in smaller tanks. This species thrives in spacious, well-maintained aquariums with plenty of hiding spots and open swimming areas.
