Sex my pleco

Looking for more of the scientific observation activity instead of something more salacious.

Wondering if this is a male or female. You can see the size based on the heater. (Click on the picture to get the full size in case the forum software throws the aspect ratio all off.)

it's a juvenile male based on the bristles on the face. Females do not have bristles.
