Peppermint shrimp eating crabs

[Taco]

I have 2 peppermint shrimp and so far they have eaten 2 of my small hermit crabs. Will they eat the bigger ones too? They just pull the little ones out of their shell and go to town!
I thought they were compatible from what I read online.

I have blue hermits and a red hermit and our peppermint shrimp don't touch ours and we have some tiny ones. Are the shrimp getting enough to eat?

I have red hurmets with peppermints and i dont have that problem but i have heard peppermints can get a bit aggressive so I got a good sized male with 2 female's to keep him occupied

Maybe get some females
