SO... due to seeing a) this talk of a snake being this weight and age compared to my tiny yearling, and b) that picture of the 100g snake who my snake looked much bigger than, I weighed him again just to be sure.
And the embarrassing conclusion to the weight issue here- I think he hit tare on my scale in the first place and I just didn't notice (it's a touch sensitive scale). 😅
Here's the new verdict: http://m.imgur.com/ThxuxbF
(He's 287g for those with poor vision.)
Is that more normal/something I don't have to worry about? Thanks a bunch everyone for your comments.
I just need to find a better way to keep in humidity, I think my heat lamp dries out the cypress mulch extra fast. (I have tin foil covering the lid and everything though).
