Bath's Blenny _ Ecsenius bathi (Orange-Striped variation)
I am surprised to see this species has two very different colorations one gray with yellow head and 3 black body stripes. It also has the Orange-Striped variation, alternating red orange and gray stripes intersected by narrow brown bars forming rectangular windows and a pair of white stripes through the eyes (taken from book Teef Fish Identificayion by Gerald Allen, Roger Stelle, Paul Humann and Ned Deloach, page 349). Seen in Parsi Tidori, Weda, Halmahera.
"Ecsenius bathi", known commonly as the Bath's comb-tooth, is a species of combtooth blenny found in coral reefs in the western central Pacific ocean. The specific name honours the German ichthyologist Hans Bath who was a notable worker on blennies and who brought this species to Springer's attention and allowed him to describe it.
