Yeah centipedes (Scolopendrids, to be precise) are very defensive. That's exactly why my pede's fangtips got clipped; the fish shop guys wanted to protect their customers' fish! I bet a medium sized fish would be killed by a feeder Scolopendra if it got bitten.
Taco - Thanks.
I've got a vid of me handling my pede but it's blurry because it was taken with a Nokia phone.
