Dascyllus reticulatus, known commonly as the reticulate dascyllus or two-stripe damselfish among other vernacular names, is a species of marine fish in the family Pomacentridae.

[1] Reticulate dascyllus is widespread throughout the tropical waters of the central Indo-Pacific region.

Although distributed across the Western Pacific, the northern population has been found to clade with D. flavicaudus, while the southern population has been found to clade with D. carneus instead.

[2] Dascyllus reticulatus is a small marine fish that reaches up to 9 centimetres (3.5 in) in length.

It is also territorial with members of its own species, and (in an aquarium context) with new additions to a tank, but does not harm corals or invertebrates.
