how bout the one native here in Thailand?
grows really fast, no need for CO2, actually no need for anything
they grow everywhere, and they're huge
edit: it appears the web says its from NA, so I suppose its an invasive species here, some MODERATOR EDIT probably threw it in the waterway and now they're everywhere
