Hi i an kieran i am thirteen years old and i have 2 corn snakes and a need to know haw hot the water hasto be?

That's not necessarily true. Most of us use under tank heaters to maintain a warm side of 82-84. If your snake room is maintained in the 80's, supplemental heat is not required. My snake room is part of the house so whatever temp the house is, so is the room. In winter that could be in the low 60's and unless I'm brumating them for breeding, I don't want my animals to hibernate. Back to the original question though...water should be at room temperature.
