I was watching my fish and something caught my eye on the glass, it was a millimeter in length, white or almost clear in colour and moved as if were gliding across the glass; once it reached the bottom/stones, it moved as if it were a worm, you know, it "slinked" around the stone. It also appeared pointy on both ends; no sign of eyes or feet - keep in mind it was very very small, and I've only seen one of these beasts - twice - it could be the same beast. Keep in mind it's very small, so catching it really would appear very difficult, I think I'd crush it. When I mean small, it's like " - " that small. I've never seen anything like it before, that is until I put real plants into the tank; it's not a snail, been there done that. Any ideas? ??? Thanks.
