Like the others have said no need for that species, but lets say you get a high humidty needing snake, I have a Brazilian rainbow, and I have a sheet of acrylic that fits on top of the aquarium, then i have holes drilled into the acrylic. I use an aquarium air pump to pump air into the tank, with an airstone at the end of the line, and the airstone goes into the water dish. This does 2 things.
1) keeps the water moving and from going stagnant
2) forces the air coming in to get pushed thru water, greatly incresing the humidty
Doing that I do not have to mist, and my humidty is around the 90% mark obviously the more holes in the acrylic, the lower the humidty
