Hello my name is Darla I'm new here. My daughter is wanting to get a chameleon and we wanted to get a panther not sure what kind. Do they really change colors with their surroundings? She was wanting to study their color changing abilities for a science experiment and I've always wanted one. If they do change with surroundings which one would be best to buy. the experiment wouldn't be til next year but we wanted to get one now to raise for next year. Any ideas?
