yea that is correct wyldfya. but to me it looks like the pleco posted by aapl has an adipose fin?!?!?
which counts the hystrix out.
 
It counts the acanthicus histrix out, which is the fish that is lacking an adipose along with its sister species the adonis. The pseudacanthicus histrix however does have the adipose fin. Which is what I am 99% certain that fish is.

yea ok thats what i thought. its hard to tell on IoStrisciare picture which it is because of where the guys thumb is. going on the dorsal though, i am leaning more towards pseudacanthicus histrix. i think it has too many dorsal ray fins, but i might have counted it wrong, ill check
 
I beleive that the dorsal rays have the same count on the two species... It is difficult with the placement of the thumb. Although the coloration does not match that of acanthicus hystrix.
 
i think with acanthicus it is less than 9, pseudacanthicus with it is 8 plus. its an overlapping area i know, but i think the first spine is usually longer on the pseudacanthicus. could be wrong though
 
Acanthicus is 9 or less or less than 9? I thought they could have 8 spines. The one problem with the picture from IoStrisciare is the coloration, which looks to be more of adult colorations of an adonis, rather than either p. histrix, or a. hystrix.

wouldnt say it was an adonis. its only about half the size of an adult

I'd agree, the size is too small for the coloration to be like that, unless it was lacking spots from the start.
