At night I have a small gray-ish worm that slithers over the bedding (crushed coral). He has a couple of white/yellow bars (about 4 or 5) from head down to about 3/4 of the way. It has a widened head like a python that has two trianles (same color as stripes) on each side. It's tail was pointed on the end. It is non-segmented, and its' skin can fold over itself or stretch like my bristle worms do. He only comes out at night and hates the light completely. If no one can guess what this is by this description then I don't think a picture will help but I will post one if you tell me where to put it. Thanks...
