With its small-oval shape and sloping forehead, the Three Spot Damsel makes a beautiful specimen in the tank. The Juveniles Three Spot Damsels are bright yellow with one spot more than adults found at the top rear on each side of the body. It grows up to 5 inches and lives up to 19 years in a tank. The Three Spot Damsel requires a tank with plenty of live rocks that encourages the growth of algae on which it can feed in between its meal. Despite its aggressiveness, the three spot damselfish has little in the way of protection against predation. The Three Spot Damsel is eaten by a wide range of reef predators including grouper and jacks, so it should not be housed with these. The Three Spot Damsel does not bother any sessile invertebrates present in the tank and can be kept safely in any reef aquarium. The Three Spot Damsel is very easy to care, and makes a good choice for a beginner aquarist. The Three Spot Damsel is omnivores in nature and needs to be given a mixed diet of meaty foods and planktivores. The Three Spot Damsel requires a tank with plenty of caves in it to hide or to take refuge when required.
