Japanese Leatherjacket (juvenile)

Paramonacanthus japonicus


Also known as Japanese Filefish. As adults, colorations vary but the tell-tale sign of this filefish is the dark blotch beneath the dorsal fin. Males become more elongated as they grow older. This species will mate monogamously.


Inhabits weedy and sandy areas of coastal reefs.


This juvenile filefish seemed to be taking refuge beside a mauve spiky soft coral. Spotted it in about 14m of water in a sand-and-rubble area at the Dayang Beach dive site. It measured roughly 1.5cm long.

I've updated this spotting with a video!

I was shooting a candy crab first, then this juvenile filefish kept insinuating itself into the frame. :D
