Hi, I'm a newer owner of a ball python (he's also my first snake, and my mom says I'm a worry wart), he's two years old, a rescue from a pet store, then another rescue from a friend. He's been eating live small rats, every five days due to him being underweight only being at 494grams. Which I know he should be doubled, although he doesn't look skinny, I just know everyone else's male ball pythons around the same age are at least more increased in weight than he is, and I don't want it causing a future problem. He's in a 45-gallon tank with cypress substrate a CHE and a UTH controlled by a thermostat. His warm temps are 86 which I know is a tad low, and cool temps are staying around 74, humidity is at a constant 67. Identical hides on both sides along with the water dish. That's all I can think of for his husbandry.
I recently noticed some raised scales that look curled up, around his neck and some closer to his tail and mid area. I read around and checked for mites under them but they look clean underneath, and he isn't spending too much time in his waterbowl so it can't be that. I read that it could be grow feeding, which could technically be what I'm doing with him just trying to get him up to the weight I feel he should be at, But does this cause an issue for my snake? Should I maybe stop feeding him so often, and allow his scales to go back down? I just wanted to get other's opinions on it. Here are some pictures (crossing my fingers they work)
