Overview

October 16, 2026 · Suggest an edit

The true parrot cichlid is the original species that deserves the name "parrot": its mouth structure and facial profile are reminiscent of a parrot. Its greenish gray–olive body has dark blotches along the middle and a dark spot on the caudal peduncle; in mature fish the lower head and throat take on reddish–pink tones. It has nothing to do with the hybrid blood parrot commonly seen in the trade. It is a rare species for experts, coming from the blackwaters of the Rio Negro and Orinoco.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 600 liters and 200 cm of length for a single fish or a pair.
  • Very soft, acidic water prepared with reverse osmosis water; a tannin-rich setting with roots and leaves.
  • Large roots, round stones and a wide open area; dim light.
  • A 30–50% water change weekly; it is sensitive to nitrate.

Diet

Omnivorous. Make a quality cichlid granule the staple; vary it with frozen shrimp, mysis, bloodworms and blanched vegetables.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

Calm for its large size; it usually has no problems with fish of similar size. It eats small fish that fit in its mouth.

Good companions: uaru, severum, large Geophagus species, discus and altum angelfish (in a very large aquarium), large tetras, plecos.

Avoid: small fish, shrimp, aggressive Central American cichlids, species that need hard water.
