Crenicichla compressiceps

Crenicichla compressiceps is one of the smallest of the long-bodied predators known as "pike cichlids". It comes from the rocky, fast-flowing stretches of the Tocantins River in Brazil. Despite its small size it is a true hunter: it lies in ambush among rocks and catches any fish that fits in its mouth. It is popular among enthusiasts who want to enjoy the majesty of the large pike cichlids in a small aquarium.

• At least 120 liters and 80–100 cm of length for a pair.
• Rock piles, crevices and caves; a separate hiding place for each individual.
• Well-oxygenated, clean water with moderate current; change 30% weekly.
• A tight lid; it may jump when startled.

Carnivorous. Offer frozen bloodworms, mysis, brine shrimp and small pieces of shrimp; some individuals accept carnivore granules over time. Live feeder fish carry a risk of disease.

Territorial toward its own kind and similar bottom-dwelling fish. It usually leaves alone fast midwater fish that do not fit in its mouth.

Good companions: fast tetras and barbs too large to fit in its mouth, Ancistrus, medium-sized corydoras (in a large aquarium).

Avoid: small fish such as neons, rasboras and guppies, shrimp, large aggressive cichlids.
