Hermit Crab and Yellow Colony Polyps

[SABOB]

Bought a Yellow Colony Polyp rock from Aquarium Designs on Friday.Acclimated,placed in tank,everything going good.Polyps opened but noticed over the weekend a Hermit Crab grazing across rock.Now there is a clean path in the middle of the polyp forest.Do Hermit eat Yellow Polyps?

How big is the crab???? If it's bigger than a blue leg, you may be in a pickle.

Have 4-5 red leg crabs no more than an inch in size.Got the crabs from B&B if you know what crabs they have.

I'm stumped then... :)

No chance the "clean path" was just closed polyps from the path of being walked on? (just hoping)

[SABOB]

No, the rock was covered,now clean.I don't see anything but rock down the center now.

I am having a similar problem with a large decorator crab and my yellow/green polyp rock. It was covered, now they are slowly disappearing and I am pretty sure the decorator crab is to blame for it.

Thanks,

All of the yellow polips that I have had, have always melted away and then came back larger and more. Just a thought
