Is this pest???

[Kaman8]

I bought a bird nest colony today and did a 10 min dip with coral rx. I found something in the coral and it will not die in the dip. I took it out of the coral and it was still alive. Is it pest? It looks like prawn with lobster claws .

It looks like a baby shrimp or lobster too me.

I would say not, but see what someone else thinks
what are you going to do with it if it is harmless?
