My RTC is a few months old and for the life of me i cant get him to eat anything but omnivore pellets, ive tried feeding crickets, shrimp, frozen smelt, earthworms everything, most of the time he wont touch anything except the omnivore pellets, when i dropped the earthworms in however he died gulp them up, however a few minutes later he threw them up. Any suggestions as to how to get him to try and eat other things?
