Ramshorn Snail Acting Weird

[eustoma01]

It's just sitting at the way top of the tank riding the waterline upside down but it's like twisting and turning its shell from one direction to the other. It was doing that earlier when I did a water change so I thought something was wrong with it and I picked it up but when I set it back down it was acting normally and went on its way.

Turned off the lights though and not long after it started doing it again. Just stays up on the top of the water upside down riding the current around the tank while twisting its shell side to side.

Is it like mating with itself? lol Or is something wrong?

I’ve seen mine do that on the past maybe there r some tasty morsels at the surface

Your snail is simply grazing on the biofilm that accumulates at the surface of the water. If there is enough available you can see it by looking from the bottom of the tank and looking at the surface and it will glisten with rainbow colors.
