One and a half year old snake, 50 grams?

[200xth]

Wow guys! After one quick google search, those are exactly what they are..spurs. My vet said "Oh those are his hemipenes" as if it was casual. I knew something was wrong, maybe he had the wrong word lol. Well I am definitely relieved.

If those are just his spurs, and there is no parasite problem or other internal health issue, the problems are most likely environment and feeding. There's a chance of a genetic or other issue, but I would guess it's most likely to the undersized food he gets.

Both are relatively easy to fix. Get your temps dialed in. This is pretty easy. Once you have your tank setup properly with temps measured and controlled correctly, you're well on your way.

Based on your shed descriptions, your humidity is off regardless of what your gauge is telling you. I would put a humid hide in there for him. They're easy to make and give him a place with boosted humidity for when he needs it.

As for feeding, once you start feeding him properly sized food on a regular basis, he'll grow. Mouse fuzzies are way too small for any BP. I see you moved him up to hoppers which is great. He will probably only be on hoppers for three or four weeks at most before you have to move him up again.

You might want to consider tracking his weight and his food weight for a while so you can monitor the growth. It's not really necessary in most cases to track weight and food weekly, but in your case it'll provide two benefits:

First, you'll have something concrete to refer to when you're trying to determine if he's making progress or not.

Second, since you're having trouble gauging proper food size by eyeballing it (no offense, but mouse fuzzies are not correct), adjusting food by weight will make sure you get it right until he gets bigger. If your snake weighs X you feed him something between Y and Z. You may think the food looks too big or too small, but if it's the in correct weight range while he's a hatchling, he can eat it. Over time, with weights backing you up, you'll start to get a better feel for eyeballing food.

Good luck with him. It sounds like he got off to a slow start unintentionally, but you're doing what you can to fix the problems and get him back on track, so that's always good.
