Crabs on Poci?

My Poci has been looking like its bleaching. I turned my LED's down to the point that my Bubble Tip An was suffering and shrinking so after a few weeks to a month of no recovery I figured thats probably not it. Ive tried to feed with no change. Today I turned the lights on early to feed some other corals and I see that both my Emerald Crabs are on the poci. Is this normal?
 
I had an emerald crab that killled one beautiful pink stylophora i had some years ago but thought it had to do with something else(water parameters,etc). After that he went to a pocci too.He almost detroyed that too.

I observed him and he was picking it.
Don't know if it was a random behaviour and i was unlucky when i bought him but after i got him out pocci recovered.
Didn't bother any other of the corals though.

The only crabs i trust and want in my tank are bandits:)
