The Blue Devil Damselfish is a great beginner fish as it is a very tough fish and is easy to maintain. The only difficulty would be that this species is highly territorial, which would include spawning sites and shelter sites for protection. They would only show aggression towards species that compete for similar environments, such as butterfly fish and surgeonfish. It would therefore be advised to only introduce this fish once other fish have established themselves. If this is considered and controlled then the Blue Devil Damselfish is a great reef fish to have and will add some vibrancy to the aquarium.
