Cichlid-Threadfin Acara (60mm)

The Threadfin Acara is a peaceful, moderately sized South American cichlid prized for its elegant fin extensions and distinctive “thread-like” pelvic fins. Known for its calm temperament and vibrant coloration, it’s ideal for community or species-focused aquariums.

🌈 Colour Development – Juvenile vs Adult

Juveniles:
