I just bought a jar 2 weeks ago, and now he's 3 inches long. i feed him 4 small meal worms in the morning and 4 at night. but 2 days ago, he started to eat only 2, and the other 2 he just drowned them. then i put 2 more, he just drowned them again. i don't know if he's just playing or something. i'm just worried that he might die because he only eat few.
