Ok, So I was looking at my tank from a distance when I notice something moving in the tank... I have a few snails in there . and at first I thought it might be one of them. but the thing that I was moving wasn't one of my snails. Let me describe this thing. I thought it might be a snail without the shell.... it's was about 1/16 of an inch wide and about 1/4 of an inch in length. It was white and almost translucent. It's slowly made it's way up to the top and then it way back down. it wasnt swiming but simply sliding along the glass. I havent seen it sine sunday, but i was curious to find out if anyone's seen anything like what I'm describing.
