Corydoras-Albino Sterbai

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:

• Pale silver or olive body

• Minimal fin extensions

• Subtle facial markings

• Often appear plain compared to adults

Adults:

• Iridescent blue and green body sheen

• Long, thread-like pelvic fins

• Distinct facial markings and orange/yellow highlights on fins

• Males develop more intense colours and elongated fins than females

Colour and fin development are enhanced by:

• Stable water parameters

• Balanced diet with high-quality cichlid pellets and frozen foods

• Low-stress environment
