I took in a new pleco today... Hes 4 years old and i was told he was a common pleco... but i think he looks more like a clown (plus hes way too small for a common from what i've seen) he's around 3 inches long and nice and fat... hes constantly munching on the algae too which makes me doubt if hes a clown as our other clown (much lighter brown) is only interested in the bogwood 
so what is he? and can we tell if hes a he?
