It depends on what you are used to keeping. I have 11 chameleons so for me they aren't difficult. They have very strict environment needs. Most phants are WC and that poses problems because it is difficult to treat them for parasites. I just got on a list for some CBs so hopefully I'll get a breeding CB trio in the fall. If you need/want a good care sheet for them I can send you one. Reading through the care sheet should be able to help you determine whether you want to get into them or not.

Hope that helps,
Amanda
