pistol vs. emerald

[Kingpin]

i have a baby hitchhiker pistol shrimp. green in color about 5mm long. he has been snapping at my emerald crab i just bought, kind of like pinching his legs.

 

will the pistol shrimp hurt my emerald?

 

BTW how does emerald eat bubble algea?sofar it looks like he eating everything around it.

Technically, the snap you hear is not from the contact of the oncers with each other, but a mini sonic boom from a tiny jet of water that shoots out of the joint. The sound and pressure are meant to stun prey.

To answer your question: no, I don't think you should worry about it.

emeralds supposedly eat bubble algae. I have never seen it, although the valonia in my tank has seemingly vanished, save for one massive bubble on my tuxedo urchin.

 

I have seen my emerald perching on the bubble algae as it consumes many other things in the tank.
