About

Astronotus crassipinnis hails from the cooler subtropical drainages of the Paraguay and Paraná river systems. It is distinguished from the common Oscar by more clearly defined vertical banding and a somewhat stockier body. Tolerates slightly lower temperatures and is an interesting alternative for keepers who appreciate species-level accuracy.

Care Guide

Water: 22-28°C, pH 6.5-7.5, moderately hard water tolerated. Tank: Minimum 350L, strong filtration, minimal décor or robust hard-leaved plants only. Feeding: Large cichlid pellets, prawns, earthworms, quality frozen foods. Behaviour: Semi-aggressive; territorial with conspecifics but manageable in large tanks. Compatibility: Best with other large robust South American cichlids.
