Overview
A small predator at around 10 cm, it suits a shady, planted tank of at least 75 litres with leaf litter and wood. Keep it at 22 to 28 C and pH 6.0 to 7.5. It will eat tiny fish and shrimp, so keep it alone or with tankmates too large to swallow. Feed live and frozen foods such as bloodworm, brine shrimp and small earthworms.
