Building a south american biotope terrarium 10 feet by 3 feet by 3 feet and I want a chameleon and I was thinking of adding a snake but I don't want my chameleon to get eaten if I had frogs I would prefer that they don't get eaten but if they are cheap I probably wouldn't mind as long as they can breed fast enough. Would they also be able to eat turtles. Also can all constricters swim.
