I have a male leopard gecko who is about eight months old now. He has been very happy and healthy up until this point. Recently, he had a very difficult shed and I helped him along with warm water and Q-tips. Since that time he has not eaten and hardly moves in his tank. His tail is getting thinner and I am getting very worried about him. I have taken him out to look over him, and sometimes he reacts by tensing every muscle in his body. It really startled me when it happened - he opens his mouth and the tip of his tail goes crazy, but every thing else is locked up solid. Is this a fearful reaction or a sign of something more?
Any advice you guys have would be really helpful. There is a female of about the same age in the tank with him - she isn't eating as much, but seems to be herself for the most part. Should I separate the two?
