First of all, he didn't sell it to us as an axanthic. We didn't even recognize it as an axanthic until after it had shed. (He was in blue when we bought him) We noticed he didn't have any yellow at all on his sides and we were very skeptical at first as well. Then we looked at a normal side by side with him and realized what we had stumbled on. The pic below is of him (the axanthic) with a normal.
