One of my hermit crabs is definately dead .. now what?

  One of my hermits just died and i dont know what to do now. Should i take out the sand that he died on to protect my alive hermits, or is it safe to leave it there?
When they pass they tend to leave a brown secretion ...

So take a small shovel, and take the sand out, just to get the secretion out.

So however he died, it won't affect the others. & They'll be fine.
He's currently burning in hermit crab hell because he didn't accept Jesus Chrabst as his personal savior. Pray for him.
Would you mind explaining how he died?
Eat it.
