I wouldn't do it with that yellow assessor in there. Any fish that looks like itself (to the candy hogfish) it will not be impressed with. I had my candy hogfish in with a royal gramma (only same sized/shaped fish in the tank) and they were totally fine. But they kept to their own parts of the tank as it was the gramma that was the aggressor. I never kept any shrimp in the tank as I had a melanurus wrasse that thought they were tasty snacks.
Beware, they can be jumpers. My last one jumped. I lost the first one to a tank move
