Sex P. brevis

Hi everyone!

I've got this P. brevis in the photos below about a month ago in a fish shop. I guess it is a male, because in the Cat-eLog of this fish the sexing section says 'Males develop small teeth-like odontodes which adorn the leading pectoral fin rays and the back half of the fishes body. Females remain unadorned and have a wider girth across the body most evident when the area just behind the pectoral fins is viewed from above.'. In the photos it is possible to see what I think are the 'teeth-like odontodes' in the pectoral fins, but, as I not used to sexing plecos I decided to ask for a confirmation.

Also they have a thicker top edge on the tail fin. I would think female, or to young, due to the back half of the fish being smooth.
Cheers
