there are so many other fish that are legal that you'll get the same satisfaction from. i wouldnt wanna risk the fine for having one of those bad boys. and with a 300gal. tank on the way, you could put a few nice fish in there rather than having a 3ft. snakehead in there ripping everything to shreds.
BTW, any lfs that gets caught that are having any illegal fish, from SH, piranhas, rays to even snapping turtles and african clawed frogs will get fined $5,000 per animal. A lfs in my area got fined closed to $80,000 plus all the fish confiscated.
I think you meant the miniature african clawed frogs that grows to only 1/2". The nice ones are the larger cousin which are called african clawed frogs but grows to about 5"-6" and will eat anything that it can swallow.
