Bad Hermit????

A couple weeks ago I bought about 10 mexican blue leg hermits. One of them wasn,t a blue leg , its a dark redish brown.
Anyone know if its good or should it be removed?
My feather duster has gotten clipped off by somthing and the maroon clowns tail had a slice in it(almost healed).
I cant think of anything that could be doing the damage, but I haven,t seen that crab do anthing either?

 

Just pull that crab out of the shell and feed it to your trigger. Guilty till proven innocent!
Well, who knows really if that hermit had anything to do with either incident, unless it was caught in the act. Sorry to hear about the feather duster, though.

 

I know it's a few days old, but mine did this too the other night- seems to be Bad Crab Season! I can't decide if he's going to the LFS or wrapped in extra nori with a little wasabi!

 

i doubt a crab did that, maybe mantis
all crabs are little devils, ive had red and blue in my tank with no problems

 

yeah I have both colors in mine as well, never touch the fish or feater dusters. They usually are too busy swapping shells.

 

Great What can I do to find out if it is a mantis
I,m really confused.
My Feather Duster either survived the attack or shedded its feathers (if that happens?)
The story is --- I found the whole top of the feather duster stuck to the Hydor pump and the end of its tube was like it was pinched shut.
I left it there(the tube part)not sure if it was dead or not and about five days ago noticed some scrawny new feathers protruding from it.
Looks like it might make it if whatever happend dosnt happen again

 

you never mentioned anything about a pump, if thats the case theres your answer.

 

Wasnt the pump --thats far away from the duster and sheilded .
