White Hermit Crab, any info?

I wouldn't recommend these as reef safe anymore. I bought 2 a while ago, big and fast moving. Both crabs decided to get out of there shells and never saw them again, I believed both are dead, then a few weeks ago zoas started disappearing overnight. I couldn't figure out what was going on. Then I wake up, 2 mushrooms are shredded. They are healing fine. Now I've lost like 1 ricordea every night for the past few nights.

 

I get up this morning, I find a piece of rubble and superglue in a hole on the top rock in my tank that wasn't there yesterday. It turned out to be a ricordea with a chunk missing out of it. Watching that rock for a while a white crab started to pop out. He is living in my rock instead of a shell. He must come out at night and drag my coral back to his cave.

 

Now how to get it out and is the other one still in my tank or dead idk

I don't think hermit crabs do that....

That's crazy. Sounds like some other critter or type of crab. Mine definably didn't do that!
