my snail has a bubble protruding from the front of its shell and is floating just off the bottom of the tank. its still alive and moving but this doesnt look to natural so I was wondering if anyone has any information about this.

The bubble showed up and by the next morning it was gone. he was sitting up at the waters edge with no bubble when i checked on him this morning. now the snail sits at the bottom and hasn't moved lately.

How's your snail? He/She wasn't laying eggs? What type of snail is it?
