The Blue Damsel is a very hardy and active fish, and with such beautiful stunning color it makes a great addition to your aquarium. The female Blue Damsel fish is generally all blue whereas the male has an orange tail and often known as orange tail blue damselfish. It prefers to hide over the crevices and holes when it is threatened, therefore lots of live rocks are recommended to be kept for them. Once the Blue Damsel perceives that the threat is gone, it turns electric blue in a matter of seconds, which explains why it is also named as electric blue damselfish. The Blue Damsel is somewhat aggressive but if given individual crevices and niche, the aggression decreases. It is a very good choice for a beginner aquarist as it is easy to care and is small in size, thus making it an ideal companion fish for reefs and invertebrates. But as it grows the aggression increases, causing problems with the selection of other species to be added to the aquarium. The Blue Damsel mainly feeds on flaked and frozen foods, and herbivore preparations. It is probably the bestselling marine fish in the United States. Breeding is possible in captivity if provided with a male and female pair. It seems to be very resistant to most saltwater fish diseases but you still need to take proper precautions and use a quarantine tank before introducing them into your main tank. After they've been in quarantine for two weeks or so and you notice no signs of illness you can acclimate them into your display tank. It is best to keep the Blue Damsel either singly or in pairs to avoid aggression behavior in a peaceful community aquarium. The Blue Damsel thrives well in temperature range of 72-78 degree Fahrenheit, and pH value of 8.1 to 8.4.

Most damselfish species accept all types of food eagerly and are very disease resistant.Damselfish are often used to break in or cycle a new aquarium. It is important to remember that even though these fish are hardy and can handle the adverse conditions of a new aquarium, they may become quite aggressive among themselves, and toward other tankmates. Most of these fish stay in small shoals in the wild when young, breaking away from the group as they grow, and eventually become solitary as adults.
