Ok I saw a bit on the ID me worm post but was hopeing for some more info. I cleaned my 20g last night and as I was sifting through the sand this peachy pink colored worm appeared. I sucked him up to get a better look at him. I believe its a bristle worm (my first one in 8 + years of havign tanks) he has small white hairs lining both sides of his body. Ive heard they are very bad and take them out immediately. Ive also heard they are ok. I have a fish only tank (unless you count the 1 margarita snail and 3 blue leg crabs) I let him go should I take him out if I see him again???
