Hi there,
I'm a little concerned about my yellow belly spider BP and as it is my first reptile I'm still learning the ropes on being a reptile mom.

I have done all my research and such but I'm just not sure on his weight. He is currently 13 months old and weights around 360 -370 grams or 0.7 -0.8 lbs. He doesn't seem to be underweight as I cant see his spine tapering other than when he is wrapping around my hand and even then its still not much. There is no stretchy skin or con-caving belly either. After doing re-search I'm still not sure if he is ok. Most of what I have seen says he should be almost 600 grams. He is about an 1-1.5" around.

I just wanted to see what everyone else thought as there are people on here with WAY more experience then me. Any tips or info would be much appreciated. Thank you!
