After his last molt, my juvie P. platyomma had been hanging out next to his waterdish alot, so I upped the humidity (larger dish, overflowed, and covered over part of the enclosure with wrap). Him being a massive pig, I put in some isopods for clean up. He ate 'em all. So I stuffed him full of roaches, tried again. He ate every single isopod. Again. What to do?
