So I have this 55 gallon aquarium tank that I had my fish in once, I want to try and set it up for my snakes. Divided into 2, besides dividing the tank in 2, how do I go on heat, what wattage for that tank how big of a uth, and I am gonna put a bunch of decoration to make them feel safe of course and cover the 3 sides, any suggestions would be great thank you in advance
