The two photos from Imazo show a fairly smooth-skinned, long-nosed fish which indeed looks like a Hisonotus.
The remaining photos show a fish with prominent rows of spikes along the sides, and a blunt nose. It is IMO more similar to than to Hisonotus (but it is probably not identical to Schizolecis guntheri; head shape and pigmentation is somewhat different).
On the other hand, the images are very small and it's hard to see much detail. So... what do you guys think?
(EDIT: To whichever mod did it: thanks for the edit. I tried to achieve this name-link effect, but couldn't remember how.
