I know insects should be a minimal part of a Uro diet... but as a treat, what type of bugs would a Uro eat? Crickets? Mealworms? I'd prefer to give him freeze-dried bugs rather than live ones... anything in particular I should look for?

Also... my Uro often has a lot of salt discharge around his nose. How much is a normal amount, and does having a lot of it indicate a problem?

Thanks
