I have a bunch of those. They don't seem bad, at least they haven't caused any obvious problems. Sometimes they will swim off into rock. Id like to know what it is also.

Just FYI to anyone else with these. Critter Category: Flatworms
This tiny creature is a Flatworm - Amphiscolops sp. This type is virtually clear, and quite small. The rounded end is inflated like a sail, and stretches in the direction it wants to travel, then like a suction cup it grabs the glass and pulls the rest of its body that direction. This is a benign type and you shouldn't worry if you see any in your tank. I've seen them on and off in reef tanks as well as refugiums, usually short-lived and forgotten later. Reef-safe.
