Calappa Calappa?

[Calappidae]

Hi new to the forum.

I setup a 55 gallon aquarium, it had: 2 condy anemones, 2 clarkii clowns, 2 yellow tail damsels, 1 sally lightfoot, a red spotted box crab, blue damsel, and turbo snails. The next morning I woke up and everything was dead except a yellow tail and a few snails. Not sure what happened whether to blame the anemones or what.. but I was sick after waking up in the morning and seeing the mass extinction...

Anyways, the red spotted box crab (or smooth box crab) was a (Calappa calappa) I got it off diver's den... I was wondering if there is any way I could get ahold of another on of these crabs? I have the diver's den picture in the attachments. Does anyone know of a website, or somewhere I can order one online? Naturally I can't travel myself, so it would have to be somewhere I can order like an online store similar to bluezoo, liveaquaria, reefs2go etc. Thank you.
