My scorpion hasn't eaten for a little more then three months now. That was worrying, but he doesn't seem that thin, he seems plumper than when I first got him but not fat like the premolt scorpions on google and youtube. I try to feed him a worm every week, but he just ignores it, or acts really aggressive towards the tong, not the worm, and sometimes even takes the worm in his claws and flings it away. Once he even killed one, just to leave the body on the ground. I just assumed he wasn't hungry. But today when I woke up I realized he was wandering about his enclosure. I thought nothing of it, until just a few minutes ago. He started rubbing his stinger, telson, whatever it is against his chelicerae and pincers. I lightly poked him with my tong and he stopped. Then he started the chewing motion with his chelicerae. After a while he started chewing on his pincers, that's him grooming himself right? Then just a few minutes ago he went into his 'sleeping' position. That's what I associate it with. Claws, legs pressed against his body, and tail curled up against his back. Just right now he started chewing at nothing again. What do I do? He's a Heterometrus spinifer, in a ten gallon tank with 4 inches of substrate. He's my first invert, so I'm a newbie in this hobby.
