what is the biggest pleco

[T time]

I agree with COL, panaque( like oddball's lucky !@#%^) does have a much deeper body structure but acanthicus is larger. lol, but each way it's like a pleco the size of a cocker spaniel.

Here's the little guy (BTW, I wear XXL gloves and the tank is 36" deep x 25" tall):

Incredible. How long have you had him for? Must have a special place in your collection and I can't even begin to imagine how big his poop is.

Oddball, that pleco is monsterous! My main question is if it decided to suck on your hand, would it tickle?
