All three of mine get kind of crazy when it's feeding time. My two adults get pretty intense, but they're sneaky about it. I had my hand over the edge of Harley's tank once, and turned around to see her covered in (my) blood dangling off my hand :P My little baby is the worst by far though. He actually had a mouth infection as a baby because he latched onto the silicone on the side of his tank and wouldn't give up and ended up hurting himself. If he even smells food in the room, he'll come out and start striking at anything that he can see moving through his tank.
