55 Gallon Ball Python Vivarium

[immortalic]

Hello, I'm looking to set up a 55 gallon vivarium for my Ball Pythons soon. I'm wondering if it's possible to put any live plants with these snakes. Also, if there is anything that can coexist with these snakes (I've heard over and over that it's a bad idea to mix species, but no question is a stupid question.) As far as the lighting/heating is concerned, I have that under control. Also, would it be a bad idea to make a very small corner a small "pond" with fish or something of the sort, or even nothing at all? just to make it more natural and seemless so that it's not like a cage, but more like a picture of a snake in the wild. Over and over I see these cages (locally) that are just thrown together almost. Made from plywood, unpainted etc, and I don't want that for my snakes. Really, I'm just wanting suggestions. Live plants and any other creature (even insects) that can coexist without harm would be awesome. Thanks!
