they are pretty calm fish if you want some thing that devours what ever hits the water you want a red or a cobra sh
yep, if that's what you're after look for a red, a cobra, or a striata, or a punctata.
Seeing as you're in the US your choice is going to be limited, but dwarf snakeheads are not beasts like the larger species.

Red devildammmmmm.. is there any single fish that is available at lfs's that would be coo in the 50 for life but still be a badasS?
