What kind of ripsaw is this?

[Jiyowel]

I found this ripsaw at my lfs. What ripsaw is the light color one. The one at the middle

Is the middle ripsaw common? The light color

Looks to be stress coloration from living in a white world. Don't think it's Oxydoras sifontesi. Not sure how Oxydoras kneri differs from Oxydoras niger.

What would you make of the substantially shorter dorsal versus the other two and also, maybe or maybe not, the difference in the lateral scutes as they approach the cranial shield?

How big are the fish? Guessing 7"

Whilst I still have not been able to find details, papers or photos for either kneri or sifontesi I do think Victor has a point with the shorter dorsal fin

5-6"

More and better pics of the full side view and the spread fins might help, as might asking on Planet Catfish.

I too have zero familiarity with any Oxydoras but niger.
