The real Streamlined spinefoot
- Scientific name
- Siganus argenteus
- Japanese name
- ハナアイゴ
- Group
- Ocean animals
- Order
- Perciformes
- Family
- Siganidae
- Genus
- Siganus
It lives widely from Japan's southern islands and coasts across the Indian Ocean and the Pacific.
How the Streamlined spinefoot lives
It is active during the day. For a while after hatching, young fish school near the surface offshore and eat plankton and other food. As they grow, they form dense schools, enter the reef and begin eating algae. Adults form groups around rocky reefs and coral reefs in the open sea, among other places.
