A 30 gallon or larger aquarium with caves and peaceful tank mates is a good environment for this slow and methodical swimmer. It should not be kept in large groups because of its aggressive behavior towards other Cardinalfish, although it does well in mated pairs. It is a nocturnal fish and may be watched using a red light.

The Flame Cardinalfish requires a well-balanced and vitamin-enriched diet of meaty foods such as feeder shrimp, marine flesh, bloodworms, and depending on its size, live feeder fish.
