Husbandry

Opistognathus seminudus Smith-Vaniz, 2004

Very special thanks for the first photo of Opistognathus seminudus to the australien ichthyologist Dr. Fenton Walsh, who took the photo in the Great Barrrier Reef (Australia)in a depth of ca. 22 Meters.

This jawfish is relatively small and pale pale with a brown mottled pattern and a black ocellus on the spinous dorsal fin.

It lives endemic to the Great Barrier Reef, from Lizard Island to One Tree Island, Queensland.

Head and body pale with irregular, brown wavy lines or oblong spots along the sides, a black ocellus on the anterior part of the dorsal fin, and a fins brown basal stripe on the dorsal and anal fins.

The specific name seminudus is from the Latin semi meaning 'half' and nudus meaning'bare' or 'naked' in reference to the naked anterior half of the body.
