FeedingAll prepared foods and live / frozen treats such as bloodworm.
FurnitureSmooth pebbles and sand with bogwood and dried beech or oak leaves to leech tannins into the water. Plants can be used but are not necessary.
CompatibilityPeaceful community tank inhabitant although it's water requirements (cool blackwater) tend to limit selection somewhat. If the aim is not reproduction then these fish will tolerate higher pH closer but still below neutral. Mature males will fight often inflicting significant damage, keep in a large area or overcrowd them to avoid this. Ratios of males to females does not seem to avert this behaviour. Overcrowded small tanks will require meticulous water management.
