Questions about pistol shrimp

[Reef Puffer]

idk about other shrimp? altho ive wanted to add a cleaner shrimp was just a little worried. i will stay tuned to see what others say. as for the hermits... my tiger pistol pops a cap in them quite often, she'll drag them in and rig their shell into one of her many structures. the crabs just pop back out, its fun to watch them crawl back out of the rubble. i have more issues with the hermit crabs trying to kill each other!
