I wouldn't put a strange hermit in my tank. Even at best, all hermits are only reef-safe-ish with Scarlet Hermits being the lesser of the evils. :lol: I keep Scarlets in my tank, they are great. I'd be annoyed if I got a non-Scarlet on my Scarlet order since Scarlets demand premium pricing comparatively.

How about Yellow Stripe Hermit aka Thin Stripe Hermit? I've seen these guys around occasionally.

Yes his legs look like your pics.

But the one I have has a different shell

Shell is irrelevant, it steals it from a snail, or picks it up after a snail dies.

+1
When it steals the new shell from a snail, it kills the snail.
So scatter various sizes of empty shells around your tank. If you have snails as well.

Yes I have snails. Should I just have one or the other. Or is both fine. Snails and crabs

your hermits will eat your snails.

For food or to steal their shell.

This is very common.

That being said. most reefers still like to have both as part of their clean up crew.

I tend to over feed so there is usually enough detritus and leftover food for the crabs to keep them well fed leaving my snails alone

However with that being said I still lose snails because the hermits want the shell I find it funny that with all the shells in my tank the hermits still want a live snails shell over an empty one

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?
