Acreichthys tomentosus

(Linnaeus, 1758)


Carl-Johan Nilsson Filefish 50-60mm, shallow seagrassbed in Bohol.

Carl-Johan Nilsson another shot.

Carl-Johan Nilsson Acreichthys tomentosus?

Arne Kuilman Acreichthys tomentosus, the white lateral band blotch is the easy distinction for this species.

Carl-Johan Nilsson Thanks Arne, confirms my thoughts.

Blogie Robillo Is this filefish Acreichthys tomentosus?

Blogie Robillo Or maybe Pseudomonacanthus macrurus?

Blogie Robillo It was behaving like it was a dead leaf...

Arne Kuilman It's got more of the markings, tail and eye of Pseudomonacanthus macrurus.

Blogie Robillo Thanks, Arne, as always!

Carl-Johan Nilsson Very cool, never saw that color variation.

Blogie Robillo Which species of filefish is this? I guess it's a juvenile (it was about less than 2cm long). Spotted at a depth of about 14m in a sand-and-rubble area.

Kati Burg I guess Arne Kuilman would know.

Carl-Johan Nilsson Bristletail? Or maybe not...

Blogie Robillo Carl-Johan - It could be...

Arne Kuilman I don't think it Acreichthys tomentosus, as this animal has a more distinct lateral line under it's dorsal fin, but I can't seem to find the filefish it is. Searching further…

Ex Liao Its a filefish but dont know what kind :)

Blogie Robillo Arne Kuilman - Maybe the juvenile A. tomentosus looks like this?

Arne Kuilman Pff, took me awhile, but I've never seen it, so that makes it difficult to find. Appears to be a juvenile Paramonacanthus japonicus or Japanesee filefish. Check out the reference photos at: http://www.starfish.ch/collection/filefish.html

Carl-Johan Nilsson Good spotting Arne!

Blogie Robillo Thanks Arne, I'll look that up! :) I spotted them again today! They seem to like mauve spiky soft coral.
