Something killing my scarlet reef hermit crabs?

[johng723]

hey everyone, I have a feeling there is something in my tank that is killing my scarlet reef hermits. I just found the second one dead, and out of his shell, which is odd since I can't find the shell for one of them. Currently I only have a clean up crew since I have a relatively new tank, and a damselfish. The cleanup crew consists of 3 tonga nassarius snails, 10 nassarius snails, 5 bumblebee snails, 10 blue leg reef hermits, and 5, well now 3 scarlet reef hermit crabs. Any ideas?

Thanks!

it could be the blue leg hermits killing for its shell or another hermit crab, also do you have live rock? i could have a hitchhicker that you do not know of

The only thing I've ever seen kill my scarlet crabs are other scarlet crabs.

Are you sure that they're dead, and you're not just finding a molt?
