Difficulty: moderate. Territorial; one male per tank. Solitary, pairs or small groups.
Set the heater to 22–30 °C and avoid swings. pH 6–8, GH 5–19 dGH suit it.
Expect 3.8–5.5 cm as an adult, living middle of the water column. A 36 L tank or larger gives it room.
Carnivore; prepared foods plus frozen or live. Feed two small meals a day rather than one large one.
