This one I found while moving things around in my tank. It looks like a big freshwater pond snail. Moves fast along surfaces.From the hitchhikers guide in this forum maybe a stomatella snail?
The second ones are very small, less than 1cm long. Very dark. They move along like earth worms (squishing themselves up to be short and fat then extending to be skinny and long), not moving like inch worms or leeches.
