General information

Plectroglyphidodon dickii, commonly known as Dick's damselfish or Whitetail dascyllus, is a small and colorful marine fish that is popular among reef aquarium enthusiasts. This species is known for its striking coloration, with a dark body and a distinctive white tail. It is a hardy fish that can adapt to a variety of tank conditions, making it suitable for both novice and experienced aquarists.

Care

Dick's damselfish are relatively easy to care for but can be territorial, especially in smaller tanks. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. A varied diet of meaty foods, algae, and high-quality commercial foods will help maintain their health and coloration. It is important to monitor tank dynamics as they can become aggressive towards other tank mates.

Reproduction

In the wild, Plectroglyphidodon dickii forms breeding pairs or small groups. They are oviparous, with females laying eggs that are then fertilized by the male. The male guards the eggs until they hatch. In the aquarium, breeding is less common but can be encouraged with optimal water conditions and a well-structured environment.

Habitat

Dick's damselfish is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are commonly associated with coral reefs, often inhabiting shallow lagoons and outer reef slopes. They can be found at depths ranging from just below the surface to about 12 meters.

This species is an excellent choice for reef aquariums due to its resilience and vibrant appearance. However, potential owners should be aware of its territorial nature and provide adequate space and hiding places to minimize aggression.
