Howdy,
If you can switch your order to Dubia (Orange Spotted Roach), I think you will be happier and better-off with them in the long run. They don't climb glass, don't get super-huge, and their legs aren't as dangerous to chameleon mouths. I've raised dubias, hissers, and lobster roaches. I still keep lobsters even though they can climb glass. Their extra-soft body and nice full-grown size is why I still keep them. I also still keep Orange spotteds and they are a reasonable balance between lobsters and hissers. Roaches in general, are easier to keep than crickets. If kept within their simple environmental, food, and water requirements, they breed well and stay healthy for many months to years. Don't worry, these are not house infesters either.
