New Paludarium

[Rebbi]

I am going to start a new paludarium in a 20 gallon tank with 70 percent of it being water and the rest being terrestrial. I plan on stocking it with 1 angelfish, some fancy guppies/endlers and a bottom feeder, for the terrestrial part i want 1 or 2 green anoles, or any other small cool reptile or amphibian and a smooth green snake/ grass snake. I will have a few drift wood branches( some will be poking out of the water and into the land) for a the snake to rest on/ curl around and a section of land that covers up some of the water, it will still allow some water to be showing. There will be lots of rock and a decent amount of soil. I don't know hat plants i want, but i want some type of moss and flowering plants and other types that are easy to care for. Are all these animals compatible, the tank will mostly be centered around the angelfish which i already have( its is around 5-6 inches tall, and has long fins). I am really looking forward to this and any tips will be helpful.
