Irena looks like a RAPTOR. It's hard to tell on Cocoa, but I'd guess a Hypo. I'm more concerned about her tail being thin at her size. How and what is she eating? I would keep them separate for sure (quarantine). Usually when an adult has a skinny tail they have some parasites or something else going on. Crickets can carry pinworms/hookworms and when a gecko is stressed they act up and cause these sorts of things to happen. Any other health issues/observations yet?
