    irresponsible behaviour like this just creates havoc!

    but its really interesting, what are the chances that a male and female were released at the same place by the same aquarist and they paired up and started breeding. I think slim...

    maybe somebody had a breeding pair and didnt realise he was siphoning out the babies during a water change - whats the chances...

    whats the chances of several different people releasing these fish in the same or nearby water systems and they managed to get together and started breeding... hmmm

    what damage would a pleco, Pterygoplichthys sp., cause to local fauna and flora? besides diversifying it...

    When breeding they may well burrow into riverbanks and collapse them, causing erosion and silt issues.

    possible... the effects of this would depend on how many pairs are in there...

    i wonder if they started addressing the problem and how :push:

    See this site: http://www.plecoinvasion.org/links.html
    I don't think this is that well researched as to the exact spieces that are invasive,
    "plecos" being such a wide essentially unscientific term, referring to hundreds of spieces found in such varied habitats.
    However the hardier types with a greater potential to be invasive are perhaps likely to be those commonly found in the trade.
