- Japanese name
- ミスジリュウキュウスズメダイ
- Group
- Ocean animals
- Order
- Blenniiformes
- Family
- Pomacentridae
- Genus
- Dascyllus
It lives from the seas south of the Kii Peninsula, the Ryukyu and Ogasawara Islands to Taiwan, the South China Sea and across the Indian and Pacific Oceans.
How the Whitetail dascyllus lives
It swims out from its coral shelter to feed on zooplankton. When resting at night, it hides between coral branches. Males make nests by clearing algae and debris, often at the base of a coral colony. Males court females by swimming rapidly up and down above the nest.
