ok that's what I was hoping for, do you know if he will be yellow until he dies? Or could he possibly darken up a tad but not he totally black?It might. The substrate might encourage him to keep his lighter color though.
It's a little young but I'm gonna say it's a male.
Ok, would you know how old? Growth rates?When young they are light colored, dark colorcomesmith age, and size. Your's is a baby.
