temps and humidity is ok and they have hides but like you said but they are new, most likely captive hatched and had to go through some stressful shipping procedures to be placed together in a 20gal in a pet store where they are constantly handled by non-serious buyers who think a pet store is a petting zoo.

maybe that could be the problem...?


p.s. oh and i agree with amy, jennifer and becky as well.
