All of my crabs are under the substrate.molting?

Molting can take up to several months, depending on the size of the crabs. What sizes do you have?

My micros took 2 months, and I hear jumbos can take up to 5 or 6 months. Keep changing food/water bowls regularly and look to see if they're coming up and eating or drinking. That will let you know if they're molting. Also, you can smooth the sand and look in the morning for footprints and shell drag marks. If you see those, they aren't molting.

I also have a small who went under a couple of weeks ago, and I've seen absolutely no sign of him, he hasn't come up and I am sure my son isn't hearing anything at night. So dont' worry, give it a few more weeks, even a couple months, and keep the temp and humidity in the same ranges you would if they were up and about. And keep the water bowls prepared too. Change the food out every few days.
I myself just put in two or three small items, not nearly as much as I feed my other crabs, but as soon as I can see he's disturbed the food, I'll pile it on!
Can't wait, it seems to be taking so long. I miss my little Jeffrey
