It requires a 20 gallon or larger aquarium with plenty of loose coral rubble as part of the aquascape, and a tight-fitting lid to prevent it from jumping out of the tank. It will rarely become aggressive towards other fish, but is territorial, and will fight with its own kind unless they are a mated pair.
The Purple Firefish will feed mostly on prey suspended in the water column, but will pick food off the substrate. Its varied diet should consist of chopped or shaved seafood, frozen food preparations for carnivores, vitamin-enriched brine shrimp, and mysis shrimp. The vibrant coloring will fade if not fed a vitamin-enriched diet.
