Abalone shell coming off

[alexytman]

What could be causing this? Is it hermit crabs? Or not enough algae?

It's for some weird reason still moving normal dispite half his shell being detached..

I’m not 100% sure on that. Don’t see a lot of abalone in tanks.

I would assume poor health or a stressor is some sort.

No sign of things like slime , stringy stuff , grossness ? That I think would be disese or infection.

Starvation is possible. And as it’s the shell , I’d wonder about you dosing the big three and the amount of corraline in the tank

It looks very clean. So Im not sure if it's a infection. No slime whatsoever. I don't have iodine test. Not sure if that's a factor. My mg and Cal is 420 and 1305. Alk is 8to9dkh.

Also nothing fell so I can't think of it being the cause. Maybe I have a gorilla crab or my Halloween hermits are just too hungry. Hope this is recoverable
