Panaque ID. Golden to Normal.

[GEV83]

So I bought this Panaque as a golden form. In my care it quickly went from golden to a dark grey and now it looks pretty normal to me. Now I am looking for an ID as far as it being a L190 or L27 or something else.

With me in the 53 gallon

Today in the 135 gallon. Has been in this tank for awhile now along with the other pleco's I got.

Mouth shot will help ID for sure but so far it look like a L190

Was afraid you were gonna say that. Not the L190 part but the mouth shot part. I've never seen him put his mouth on the front glass. Well I gotta do a WC today so I'll see if I could catch him and take a quick mouth shot.
