The Blue Devil Damsel is a remarkable addition to the tank or reef aquarium. Its common name is Neon Damsel. Scientifically known as Glyphidodontops Cyaneus, it is best to keep the Blue Devil Damsel in pair of male-female in smaller aquaria. A large group comprising of a single male along with numerous females can be easily housed in a spacious aquaria. The Blue Devil Damsel is considered quite hardy and completely secure with invertebrates. A natural hiding place with lots of coral life and rockwork in a characteristic reef set up will work ideally in the aquarium. As the Blue Devil Damsel matures with age, it tends to get more aggressive towards certain placid species, like cardinalfish, blennies, small gobies and firefish. Therefore, aquarium mates should be chosen with utmost care. Newcomers to the aquarium can be harassed by the species, therefore it is recommended to make the fish, the last addition to the tank. The Blue Devil Damsel accepts a variety of diet, comprising of small frozen foods like Mysis shrimp, Spirulina-enriched brineshrimp, neatly chopped krill along with herbivore rations and marine flake food. The Blue Devil Damsel will nibble upon certain sort of algae. It has to be fed thrice a day. The species will often reproduce in captivity, however, rearing the fry is quite difficult. While the female Blue Damselfish is entirely blue, males boast of an orange tail that makes them known as Orangetail Blue Damselfish. These are also known as Blue Devil Damselfish. This fish is a great addition for all beginner hobbyists as it easy to take care of Blue Devil Damsel. Novices enjoy its small size and hardiness, while advanced aquarists appreciate the activity and color of this Blue Devil Damsel.
