Red wolf all the way.
HardCandy;2539310; said:He did mention that he wanted a fish like piranha and snakeheads except they're illegal. A wolf fish isn't as dangerous as a snakehead or a piranha.
Also, I highly doubt the kids would put their fingers in the tank if the teacher mentioned that you can lose a finger or a chunk of flesh from these fish.
