Pleco's That Get Bigger Than Common Plecs?

[onidrase]

Title says everything

Are there any plecos out there that are bigger than the 2 footer common plecos?

In trade or otherwise

I'd find it a little saddening if the biggest species of pleco was also the most widely available and cheapest to buy

adonis plec i think can push 1M. somebody i know has one, though obviously its not a metre long yet.......

A. Adonis and A. Hystrix certainly do.

Some of the larger Panaque do, titan and schaeferi as examples.
