A Question from a new Collector

[Sparda]

Hi everyone, I just have a question that I would appreciate all advice on. I purchased a corn at a show on March 2nd. They told me that he was 6 mos. old. He is very small next to my other corn who is approximately 7 mos. old. He is very slender almost like he is not very old. Well he has been eating pinkies every 4 days, but today I found a pinkie in the viv that had been regurgitated from Tuesday feeding. I try to pick out the smallest pinkies for him. Is there anything else I could do? Also he never, ever comes out of his hide on the warm side of the viv, only when I take him out to handle him. My other corn is out exploring almost every night, except on feeding night and somtimes the night after. Could there be something wrong with the one from the show or is he just to small? Any advice would be greatly appreciated. Thanks
