we recently got a hermann's tortoise and he seems healthy and happy with a regular eating pattern of t-rex tortoise dry formula. i also dampen this with

water I also dust over the top with nutribol to help his growth etc. but he won't drink water. we have left a bowl of water and he doesn't touch it he won't eat vegetables either will the water content in his food be enough or will he dehydrate? :S
