Dascyllus aruanus

Identification	White body divided by 3 black vertical stripes. Slight hint of blue sometimes on the fins.
Maximum Length	3.1″
Origin	Indo-Pacific
Minimum Tank Size	20 Gallon
Reef Compatibility	Ideal for the reef aquarium; will not harm any invertebrate tank mates and will eat some algae.

Behavior

They are cute as juveniles and hardy enough to be used in starting new aquariums, but can grow into a real terror in a community tank. Young specimens can be kept in a group but as adults they will fight, unless they are a male-female pair.

Diet & Feeding

Meaty foods, including Krill, Mysis Shrimp, and vitamin enriched brine.

Cautions

Will also fight other damselfish and will pick on docile tank mates. Best kept in a moderately aggressive community tank with larger dottybacks, angelfish, triggerfish, and puffers.
