And you thought your little pleco was cute ..............

[ILLUSN]

I have to agree with Proteus, while i see they causing nothing but trouble in that lake I'd love 1 or 2 big healthy ones like that for a couple of my tanks tanks.

[sammigold]

Pretty amazing sight!

[DiscusEden]

Here's hoping the lake's contained!

They could supply a hemisphere with that lot, if they could catch them.

[taksan]

Holy crap! some of them look huge! How would you go about trying to fix that problem?

There is a problem?
I didn't see a problem at all.

[SandyLynne]

I felt very sad watching that video clip, it was like seeing rats take over and leave nothing in their tracks.

[Bald_noggin]

Sounds familiar, European Carp...

[Robdog]

I didn't see a problem at all.

Ditto. I don't see them doing too much damage to anything. Except themselves from fleeing the diver

[Mattzilla]

introduced species.....massive population.....

i see a huge problem with them eating food supplies of native fish, poluting the water with their waste....and who knows what other damage they are doing???? like sandylynne said it reminds me of rats in plague proportions!

you can't be serious saying you don't see the problem...wake up to yourself....

dont think that people read this part These South American fish are invaders of the Ucimacinta river basin in Chiapas, MX. think you just sew the plecs swimming think it was a natral inviorament guys , but what the clip is showing it how the fish afect a area when they are introduced . scotty

[Merrilyn]

Indeed Scott. That's exactly right. The fish were introduced into a pristine environment with no natural predators, now there are no native fish, and no vegetation and the water is full of pleco poop and nothing else.

Seeing thousands of plecs swimming is an awsome sight, especially for a catfish lover, but you can't deny the devistation to the environment.

Worst of all, this is a river basin, and there is only one place for the plecs to go, and that's upstream.
