4 Stripe Damselfish (Dascyllus aruanus) Care
The 4 Stripe Damselfish, (Dascyllus aruanus) is a great starter fish for a beginning marine hobbyist. Besides being a beautiful fish, the Black-tailed Dascyllus or Four-striped Damselfish are hardy, they will readily eat just about anything, and they are not expensive.
The coloration of 4 Stripe Damselfish consists of white and black vertical bars, covering the length of the fish. There is usually a total of four black bars and three white bars with a small white spot just above the lip of the fish.
The Damselfish can grow to be about 3¾” and can be housed in aquariums as small as 30 gallons with plenty of live rock. These cute little fish are territorial and once acclimated to an aquarium, they consider the entire tank to be “their” territory.
These fish are reef safe and will not bother coral or invertebrates, but may be very aggressive towards other fish.
This species is happiest as a pair or in a shoal. A shoal should consist of one male to five or more females. When a male is needed they can change gender from male to female. They love to hide in stony corals with branches when available.
