Different crab in my order?

Like I said, Scarlet Hermits are the lesser of the evils. I have 15 of them in my 50-gallon tank along with a few Astraea, Mexican Turbos, Ring Cowrie, and even a few Cerith. The Scarlets don't touch them. There was one Blue Leg Hermit in there and he killed off most of the Cerith before he got banished. Generally, the bigger snails are resistant to hermit predation.

How many are required? I have a 90gallon. And I was reading on jlaquatics site and they recommend 70 crabs and 60 snails? Is this correct?

No, their numbers are ridiculous. For your tank I would recommend something like this:

12 Scarlet Hermits
6 Mexican Turbos
6 Trochus (different species of Turbo)
10 Astraea (get some spiny and some pyramid if you can)
12 Cerith (these are the most likely to get eaten by hermits, but they are one of the only true detrivores)
6 Ring Cowries
1 Black Brittle Starfish
4 Fighting Conch or 2 Orange Lip or 2 Strawberry Conch (if you have sand)

Buy half now, and the other half in a couple months. The variety covers all the reef needs.

Well I have the scarlettes, Mexican turbos, astrea,(pyramid) and margarita. I also have a anemone and a few corals.

So why are you wanting to order more CUC? Now I'm confused.

I would also say that left handed hermits, or zebra hermits are about as safe as they come.

They also stay very small.
