I think feeding on a broad basis helps. I get salmon (from wal-mart) and cut it up to appropriate lengths, then take a couple of scopes from the reptile vitamin mix i buy, and two pinkies. This makes sure that my pair each gets a pinky, along with enough calcium and vitamins. Now I own 3.4 I'm sure I will have to increase that, but you get the general idea. Variance helps keep their diet under control. I know I couldn't live off of hot dogs. Although it would be cheaper
