Lethargic Blue Mystery Snail

I currently have 2 mystery snails in a 10gal tank with just one betta, recently my blue mystery snail has become very reclusive and almost never moves, he was originally the most active snail and spent most if his time fully out of his shell, I haven't had him terribly wrong and am very worried about him dying, if anyone knows why he's acting this way, or anyway I can help him it would be greatly appreciated.

 

How old is it, and what temperature is the tank? They move less in cold water, but live longer. In a hot tropical betta tank, they only live 1-2 years.

I keep the tank around 70, I'm not sure how old he was when I got him, but I've had him for about a month and he grew rapidly and then suddenly stopped around the same time he started being more reclusive.

 

It could just be hungry, or being bothered by the fish. My original apple snails kept themselves hidden away because the fish kept nipping their antennae.

 

What are the tank parameters and what have you been feeding?

 

How big is it? If it's bigger than a quarter, it could just be getting old.
