Questions about pistol shrimp

[SkunkClown]

Hello

I have a yellow watchman goby in a 200g reef tank and I would love to pair it with a tiger pistol shrimp (or any pistol shrimp species). I just have a few concerns

-I have two skunk cleaner shrimp and I heard pistol shrimp may attack and eat them. There is also a nature clip with depicts this in the wild. Does anyone have experience with keeping cleaner and pistol shrimp together? Also any danger to hermit or emerald crabs?

-I have a crushed coral substrate so much coarser than sand. Will the pistol shrimp do ok with this or do they need sand to dig a burrow? Right now the goby lives in a hole in the live rock. I think the hole is big enough for the goby and the shrimp. Not sure if they can live in such a hole together or if it needs to be a sand burrow.

Thanks!
