Those things are still cute, you can still put your hand in there w/out fear....Once they get to the 16-18" mark then I would tread lightly, but usually if they are well fed they won't bother you, they seem to know their owner well.....I have had several Red Snakeheads and have yet to be bitten, thank goodness... I know someone who was bitten by a 14" still a baby by SH accounts, and it did quite a number on him....
