it turns out i've been hosting a really big bristleworm in my tank. my dad has mentioned seeing a worm/millipede thing before, but i saw it today, it's BIG. like 6 inches to a foot long (not sure). it's gray with white bristles, and pretty thick too. i almost caught it with tweezers but it crawled into some rock. would a normal bristleworm trap work on one this big, or do i have to rig something up? i also found my remaining emerald crab eaten up right near the worm's rock, so i'm assuming this worm is the culprit for both of my emerald crab deaths. so, build a trap, buy a trap, or any other suggestions?
