Welcome to What in Neptune’s World – a column intended to explore the wonders of the coral reefs in an entertaining, interactive manner.

This month, we have a mystery fish seeking identification. The
answer will be announced the General Discussion Forum the first week of
the following month. In the meanwhile, feel free to discuss the
possibilities with other hobbyists in this thread in the Reefs.org’s General Reef Discussion Forum.

Can you identify this animal?
