ballpythonluvr and Monster Dodge: I've had them in naturalistic cages before and they were almost impossible to spot. They really camouflage perfect with natural wood and twigs...very much sit and wait predators and don't move very much.
Boanerges: You should look into getting some...they are never aggressive (aside from my prego Candoia), only need to eat once a month, stay super small, and are one of the rarer ones you'll find....a great boa to keep
