its just a question of curosity why are they called "pitbulls"?the name seems to sugest agressive habits but the ones i have are obviosly not

I'm not good at identifying plecs but I had no idea at first on how the pitbull plecs look until Xingumike mentioned that this fish is the pitbull plec. Why it was named 'pitbull' is beyond me.:dunno:

Where do any common names come from?

Interesting question though because as you stated they are about as aggresive as daisy, and certainly don't look like any pitbull i have seen.

With plecos some of the common names make sense straight away, e.g.

zebra pleco
green phantom
bristlenose etc

but some make no sense at all, weird aint i?!?! :?

i mean where the heck did they get Shampupa Pleco from?? always makes me laugh that one
