Has anybody ever had any in their system. i think i have like 5 or 6 in mine i dont know whether to kill them all or leave them be. im still not sure if one killed my peppermint shrimp or not but they do clean up dead stuff and left over food. if i dont hear anything too bad ill just try to keep them if i do hear something really bad im goin to move the rocks they are into my refugium.
I would get them all out. They will rearrange your rocks for starter's and get really large-6Ft or more. Their bristles can sting and some varieties have "hooks" in their mouth and these can also sting. I don't think they bite per se. I've heard they will eat your zoo's, rics and fish when they get big, shrimp too.
