Dang the anacharius? in your tank seems so thick and bushy!!!
The snail seems to be a ramshorn snail. Be careful with it as it can breed by itself and overpopulate the tank very quickly.
However you spell it lol, it seems to like being right next to the light! I just hope I can get the rotala to fill in on the other side.
The snail also has some dark spots across it that you can just barely see in the photos, I hope it does multipy because I still have just one after about three months, it was about the size of a comma when I first noticed it.
