When I was little, I would have small, and hardy species that just looked natural in their tanks, Bombina orientalis, Anolis carolinensis, and Terrapene carolina. I don't like it when they are in too small tanks, don't even like the 10 gallon minimum rule, honestly, if you can't afford a 15-20 gallon tank, just get a Tupperware storage bin. Has all the space, just sacrifice viewing for animal happiness. I've always wanted the newts and salamander species that I'm after, because I remember going to my Library, and checking out this children's book that had drawings of Salamanders and newts, a hellbender stealing a fish off a line, an ensatina dropping it's tail, but the Red eft was just so beautiful, and they lived in my state, just made me have an approval not only of herps in general, but wherever I moved, I'd want to find and protect the animals if they were endangered, or at least in a way that a 5-6 year old could do
