Whenever I see it, I travel to another room to get something to capture it with and then it's gone by the time I come back. I have plans for it to go in my scud tank. I managed to take video of it (but when i went to get a cup to put it in it's disappeared:headshake2, just hope this will varify it's identity.
I just caught and disposed of two a few weeks back, and I another today. Then I noticed what could be babies (...or, maybe just planaria...) crawling around the glass.
I'm so blaming my recent sudden snail deaths on them.
