Acarichthys Heckelii (12–15 cm) – also known as the Threadfin Acara, a stunning South American cichlid with flowing fin extensions and peaceful temperament.


The Acarichthys Heckelii, commonly called the Threadfin Acara or Heckel’s Threadfin Cichlid, is a captivating freshwater species native to Amazonian river systems in South America. Renowned for its elongated fin extensions, iridescent silver body, and elegant red and blue highlights, this cichlid adds a touch of sophistication to large aquariums.
