Sadly he died, we didn't know he was in the rock, we were more concerned about the Eunice (which still evades us). Had we have known, I'd have kept him until someone wanted him. We are new to all this and only have a 22 gal nano, so no sump. Any tips on Eunice worms would be greatly appreciated! The one we have seems to have moved, unsure if the stay in the same burrow for life? If they do... we have two.
