A few months ago I would find 1 or 2 on the glass when the lights come on. They would retreat to the sand bed and off the glass within a couple of hours after lights on. This morning there were 5 on the glass. I have searched the internet for flatworm photos and can't seem to find any that are perfectly oval shaped like this. My snails have been reproducing every 2 to 3 months but no shell on this critter. largest one I have seen is about 3/16" or 5mm. My tank is LPS and softies and all are happy and non of these critters are on them.
Any idea what these may be?
