Top side pic then the under side. Has a mouth and two tentacles from its head, it's an inch all around. Some type of flatworm just not sure if it's a safe one. Doesn't matter just curious, he's gone anyways. Found him in my filter floss.
I'd rather rely on my wrasses than go the flat worm exit route especially if im only seeing one. Plus this is the only one I ever saw and it was in my filter floss overflow box.
