And the "don't mix species" thing includes green and brown anoles. Browns are larger and more aggressive than greens and that will lead to trouble. You're best with three (or fewer) females of the same species. Males don't mix, and male/female combos can be ok in a well-planted tank, if you don't mind a million babies cropping up.
