sexing pitbull pleco

[mommytron]

i guess it doesn't really matter it's sex, but i'm just curious. i read this

Gender: Males have longer pelvic fins, the tip of which extends beyond the origin of the anal fin, the urogenital papilla is positioned just after the anal opening in males. In females the tip of the pelvic fin does not reach the anal fin origin and the urogenital duct opens to the inner cloacal cavity.

this is my pitbull pleco, whom i have always referred to as a male.


this is "it" when we first got it

and a recent picture:

so what do you think? i think it's a female... may have to rethink the name "Calais"

I'd vote female as well. I went through looking up some pitbull plec pictures, and found a few of males, and their "front pair" of fins do clearly overlap the joints of the "back pair".

Not a expert, just spent some time looking.

But more importantly, don't let your pit bull see it, or she might start asking for designer pellets and bottled spring water! Fame goes straight to their heads!
