Hitchhiker urchin

I found an urhin in my sump. I think it is a rock-boring urchin (Echinometra mathaei) and is about the size of a quarter. I need to move it from the sump, it almost got me while I was pruning chaetomorpha. I am thinking of puting it my main tank or destroying it. Anyone have experience with these ?
