I did a quick test and put her near him (through the glass obviously, didn't want anyone to get hurt!) and he went puffy and light browny yellow....she went dark green with black spots. I took the hint and moved her away immediately!
Thank you! Yes, I am only young, but that doesn't mean I can't be mature and responsible with a pet reptile. I do have concerns, and I apologise for asking on 3 different forums (I was just rushing for answers!). The X-ray should've cost £40 but the vet only charged me for a consultation...
