General information on Orangetail Blue Damselfish
Females are all brilliant blue while the male sports an orange-colored tail. It’s a colorful and hardy fish. Wild, Blue Damselfish are found in reefs and are usually active in protecting a small area. It is believed that the Blue Damselfish has the ability to hide in a crevice before darkening to a dark black. It usually happens whenever it’s threatened. When the threat that it perceives is eliminated it turns electric blue in a matter of minutes. It is a bit aggressive, and its enclosure must be able to handle multiple species. It’s an excellent fish for novices and is the perfect companion fish for a medium-sized saltwater tank. It also makes an excellent companion to coral reefs as well as invertebrates. As the aquarium fish grows older, it could become aggressive and cause difficulties with additional tank mates. If it is kept with other damselfish, give them several hiding places to divide areas and reduce aggression.
