just when i thought i had it all figured out another twist! well my argentine black and tegu i purchused late october was about 10-11 inches is growing like crazy, he/she is almost 2 feet already. after handling the tegu today noticed the whole underside of the tegu is turing orange/red, does not look like any fugas,or substrate coloring, has anyone seen this with thier tegus? do you think it could be a red blk/wht mix? all comments welcome!!!
