Never mind! They came out a little bit ago. We are going to get some more sand now so we can add more substrate. We have enough coconut fiber, just need more sand. We dunked them all and took pics. They are definitely not PP!
Here are our babies

Meet Yui

And this is Stacy

And last but not least, Crabby!
So, what kind of hermits did we get and what set up will work the best? Thank you for all your help! Can't believe we messed up this bad
We have a ceramic heater - temps at 74-71 right now. Although we just had the top off to bathe them. Temp was at 78 before that.
Humidity is at 53, but we just got the thermometer/hydrometer so it's still coming up.
We have two thermometer/hydrometers calibrating right now so we will swap them out when they are finished to make sure we're getting correct readings.
I'm thinking I like the coconut mat only because it seems to be adding to the humidity. If we end up getting an uth, we can put it behind the mat to boost humidity plus it'll boost heat - if it's needed. We don't have room for a moss pit, but once tanks are on sale at petco!
Thank you so much for your advice. We just want happy healthy pets
