does anyone have any kind of enclosure ideas for a hingeback torotise...in doing research, i've heard everything from a 20 long to 3-5 square yards per foot of carapace...has anyone ever kept them? also, where do these numbers come from, are people just guessing? trial and error? or is there some kind kind of research or equation behind it? also, has anyone ever bred them, b/c no matter where i look, i can only find wc specimens and it seems like an animals that is imported so often should have a cb populace.
