I'm not sure what this is or if it is a bad thing. But I saw it crawling around some live rock of mine last night. Looks like a worm with about 200 legs or so. This is my 20 gallon with no livestock (well maybe it does have livestock since this is in there...lol.)
If it is a bad thing...how can I get rid of it?
