Domino Damsel (Dascyllus trimaculatus) Care
The Domino Damselfish, Dascyllus trimaculatus, is also known as the Threespot Dascyllus. These fish come from the Indo-Pacific region. They are entirely black with three white spots, one on each side of the body and one on the top of the head.
Although damselfish are colorful, hardy, reef safe, and affordable, these little fish can be very feisty and overly aggressive. These particular damsels will typically focus their aggression on members of its own kind versus other species.
Damselfish are omnivores and require a diet rich in both meaty and plant foods, such as mysis and brine shrimp, marine algae, and flake food.
The Domino Damselfish can grow to be about 6″ and can be housed in aquariums as small as 30 gallons with plenty of live rock. They will do best housed with large angelfish, tangs, triggers, and dottybacks.
These fish are reef safe and will not bother coral or invertebrates, but may be very aggressive towards other fish.
