it doesn't look like a comp to me. There is no terminal band of dark tissue on the tail and the body is not laterally compressed enough, indeed it was mistaken for the elongated gibbus a moment ago. The jaw does not appear to be upturned in the same manner as a comp too. Comps sort of have a frowny face.

In the last pic it looks like a dead ringer for a sanchezi, but if you say the scutes are orderly then it most be some sort of Rhom CF or something none of us have mentioned so far. If you squint right, it sort of looks like other unclear photos of irritans. The tail suggests this also.

If you somehow lucked up (and I doubt it) and bought an unlabeled S. irritans for 15$ then i think you will be the most envied keeper on MFK.

A note on sanchezi scutes:

at any rate without better pics, and maybe even DNA analysis the chances of us conclusively identifying this fish are slim.

The more I read, the more I'm convinced this is a Sanchezi. Part of the problem was I didn't know how uniform/jagged the serrae should be. I'm certain now that it is a Sanchezi.

Thanks for all your help and the excellent link.
