We caught all kinds of stuff. But for reptiles if their head was bigger than a nickle or it was big enough to eat a chicken egg or rabbit kit it was ant food. I caught all kinds of water critters though. I liked crawdads until we had 3 or 4 "escape". I ended up finding the last one hiding underneath a low shelf in my closet 3 YEARS after it escaped. I dont know how we didn't smell it.
