Snakeheads are only illegal in Ontario, legal everywhere else...
King eds has channa bleheri, awesome looking dwarf snakehead.
C. bleheri grow too small for a snakehead. I kept them before, they rarely pass 4". But awesome fish they are easy to breed.
Below 4" they grow fast and start slowing down at 5-6". Male actually grow faster than females. The biggest one I got was 7.5" male.
