How do you mate hermit crabs easily?

, First you buy two hermit crabs a male and female to check if its a female or a male wait until the hermit crab comes out its shell and flip it upside down and if it has two holes on it fifth pair legs then its a female if it doesn't its a male. Next, go to the dollar store or somewhere and buy a kitty pool. After that, go to a pet store and buy Calci-sand and put the sand in the kitty pool and layer it like a hill. Now put salt water in the kitty pool not too much just enough to make it look like a beach and make sure there's sand at the bottom of the kitty pool. your almost done now all you have to do is put your hermit crabs in there with a bunch of little shells so the baby hermit crabs can go in them when the turn to land hermit crabs. this process will take a bout 2 months oh and don't forget to get a heater, food and guard rails just in case. there are other ways but this is the cheapest way you'll find on how to do it.

Thanks
