I posted earlier that I got a new BP in this morning. I noticed that he looked thin, but it wasn't until I got home from work and had more than a few minutes to look at him that I realized just how thin he was. He looks like some of the rescues people post pictures of. He's very triangular. Most of my 2010s haven't really filled out yet so I can see their spines, but they eat well, are mostly round and have been gaining weight just fine. This guy just looks like he's been severly underfeed. He has no roundness to him. The seller I bought him from had great reviews here and on fauna classifieds, so I'm not sure what to think. My next feeding is this Saturday and usually I would skip the first feeding for my new addition, but he's so thin I feel like I should offer him food anyways.

I'm guessing he's thin for one of three reasons: 1.) he's a bad feeder, 2.) there is something medically wrong with him or 3.) the seller wasn't feeding him properly. He seems healthy, no signs of RI or mouth rot. He's active when held, which is actually unusal for me as most of my younger BPs like to ball when distrubed. I'm not sure what to do, I can't have a fecal done until I feed him because I doubt he has anything in him. What should I do? Should I try to feed him Saturday? Take him to the vet? Any advice would be great, thank you!

My camera batter is dead, I forgot to charge it when I left. These are the best pics I got this morning that show how thin he is:
