Minimum Tank Size: 30 gallons
Max Size: 4 inches
The Three Stripe Damsel, Dascyllus aruanus, also known as the 3 Stripe Damsel, are often found in the wild around staghor Acropora thickets in large numbers. As juveniles, the Three Stripe Damsel will sometimes live in harmony with sea anemones but as they mature will grow away from this symbiotic relationship. The Three Stripe Damsel's name gives away its primary aesthetic feature: three thick black vertical stripes through a slick white body. It has black pelvic fins, a pale caudal fin, and translucent pectoral fins. The Three Stripe Damsel is very easy to care for. As it matures it may become territorial but this can be deterred by adding the Three Stripe Damsel to the tank last. They do best in tanks with plenty of live rock as they will spend much of their time in and around it. The Three Stripe Damsel eats an omnivorous diet consisting of algae, microscopic inverts, and zooplankton. Males are larger than females. Multiple Three Stripe Damsels can be kept but, if you want to keep more than one Damsel species in the same tank, it is best to ensure there is plenty of open swimming space and live rock allowing them places to hide. They are generally not compatible with overly aggressive fish or overly fragile fish.
