Hey guys

I'm new here and I just wanted to find out a few things before i get my first garter snake.

I'm planning to keep it in a 20 gallon High tank (24"x12"x16") with an incandescent spotlight bulb for heat. I'm going to use paper towels for substrate most likely, for ease of cleaning.
This setup is fine right?

I also wanted to know the differences between the temperaments and care of garter snakes vs ribbon snakes.

I'm going to be moving to staten island soon so i will hopefully see snakes there. (btw, does anyone know any good places to find snakes around there? I found a garter snake in Clove lakes park but it was dead, looked like someone stepped on its head.)
