Sling molting

I just recently bought a 1/4 inch G.pulchripes sling. First sling Its refused food for the last three days ( I'm feeding tiny crickets that are about the legnth of his abdomen ) and it's abdomen is nearly black in color. These are signs that he/she is about to molt correct? What I've been reading says those are signs, but I just want to be sure. Also is there anything besides keeping the temp between 76-80° and having a decent amount of humidity that I should do?

P.s I have a picture if it'll help

Yep its definatley gonna molt :clap:. Just try not to disturb it too much and make sure it has a source of water to drink from. Dont use a water dish though because a sling that small could drown. It can drink from wet substrate or water drops on the side of its enclosure. You dont have to worry about temperature too much, room temperature will be just fine. If you want too you could keep the enclosure just a little warmer. But DO NOT use a heat pad! Congratulations on your first sling
