Getting another snail

First of all, I’m going to buy a nothing heating pad cuz the temp in my tank stays around 19-20 degrees Celsius and my snail needs it to me around 24-27 degrees so I need another one.

I have a Achatina reticulata albino, get it about a week ago but I realised I want a buddy for him. I know he probably isn’t lonely but idk I feel sad for him cuz he’s alone.

Could I introduce another snail of the same species to him? Or is that a bad idea?

Also how can I keep the humidity up cuz it goes down a lot and then I spray some more water in.

Any tips are appreciated!!

My snails name is Aragorn Balbinus Bombadil the second (the second cuz my hamster is also called balbinus)
