What did I just see?

[Avengerx77]

I was feeding as usual just a few minutes ago, when I see my cleaner shrimp at the bottom looking for some food. Then he climbed to a rock and while he was grabbing some pellets, he started to release some green liquid…what the heck? I have had several ones in the past but have never seen such things. Is that their way to pee/poop? Dont think he pulverized a green pellet into oblivion, so my last thought is their way of going to the bathroom? Any ideas or confirmation on my suspicion? Otherwise I am out of words.
