i also live in flrodia. anyway, im sure it might work for a little while but still a tegu's might see the movement out of the corner of his eye and then accidently chomp down on the tortoises head, why risk a very expenisive tortoise?. although that would make a really cool display cage with a tegu and redfoots. redfoots are a lot of fun and have a lot of personality, and they really enjoy the weather in flrodia.
