Dascyllus trimaculatus – Three-spot Damselfish

Dascyllus trimaculatus, nicknamed the three-spot damselfish, is a fish native to the coral reefs of the Indo-Pacific. It is distinguished by a stout, brownish-black body adorned with three distinct white spots: two on the sides and one on the head. Its arched back and powerful swimming make it an elegant and robust fish.

Unique behavior in juveniles

In young specimens, a temporary cohabitation with clownfish is sometimes observed, particularly in anemones such as Cryptodendrum adhaesivum. This fascinating behavior allows juveniles to benefit from natural protection in their reef environment.

Group living and hierarchy

This fish preferably lives in a structured group of at least 5 individuals. A hierarchy is quickly established, limiting internal aggression if the tank is well-decorated and spacious enough. It is recommended to introduce it in an aquarium of at least 300 liters, offering rocky areas, hiding spots, and large swimming spaces.
