Waterfall

So i'm pretty new at the whole snake thing here so bare with me.....

it's ok for me to have a waterfall in my aquarium right? not really for humidity or anything it would just look better :D . and take up some room.

it might make the cage to humid... thats not a good thing but if your humidity in the cage doesnt get above 60% then your fine. the snake really doesnt need it though.

I imagine it'd be a pain to clean (it needs to be disinfected weekly) and snakes are experts at moving things and dumping them over.

Honestly the less stuff you put in the cage the better. More "furniture" means more to clean each week, but if you don't mind the extra work and your humidity is still good with it in there then go for it! He/she will let you know if they don't like it by either knocking it over or getting the water ALL over the place and I mean ALL over the place.
