anyone wanna add some video/article or picture proof of their nominated species?
I already posted proof of ATF killing and eating fish considerably larger than they are.
The candiru proves you don't have to be the biggest to be the sacriest. I would worry more about them than a Pima, Gar, Stergon etc.
True. They might be something to be afraid of, and rightly so, but I don't think they count as the ultimate freshwater monster. In a one on one fight they'd be a prey item for most of the fish listed here.
