I've actually been feeding smaller crickets than I normally would because I've introduced my two juveniles into the same terrarium.
I'm going to keep him in my spare tank for at least a week after I hopefully get this resolved. When this happened before I tried feeding him softer worms and he wouldn't touch them, but I don't want him to starve for a week. Any ideas what else I could try in that time, or just really tiny crickets?
