Being a worried snakemom - is he dehydrated?

[mousch]

This is just my best educated guess (I could be wrong)\


I am inexperienced with hatchlings, but he looks really underfed. Possibly dehydrated too. Have you fed him yet?

Sorry, forgot to include the following: I picked him up today. He hatched about 4 months ago. So he won't get fed until next week, unless he looks like he's starving? He doesn't go limp when I moved him - he grips whatever he is near.
He was on live hoppers. The breeder is the one who produced him.

He is also going to be left alone for a good while now, to acclimate to his new surroundings and keep the stress down. Could I feed him earlier? Or will he be okay until next Saturday? Should I go for tuesday or something?
