ベニオチョウチョウウオの写真
Yellowback butterflyfish

Japanese name: ベニオチョウチョウウオ
Scientific name: Chaetodon mertensii

Characteristics

Very similar to the latticed butterflyfish, but can be distinguished by its non-intersecting lines.

Despite the Japanese name Beniyo suggesting red, the tail is actually orange; the redtail butterflyfish is the more red-colored of the two.
