Tiger Pistol shrimp, YWG, Firefish and Orange Blenny in one cave

[Nemoreef]

New tank and I added a yellow watchman goby first and it was by itself for a few weeks. I added some more fish yesterday and one was a tiger pistol shrimp. It immediately went into the same cave as the YWG and never saw after. Some time later, I saw a firefish using the same cave as a bolt hole. Haven't seen the TPS or YWG since. Now this morning, the same cave is guarded by a Orange spotted Blenny. This guy is somewhat large. Is he blocking all the others inside the cave? Should I do anything about it?

How big is the tank? Are there a lot of cave choices in the tank?

It's a 55G. There are more options for caves in the front and back. I made this cave for YWG and pistol shrimp. Blenny is being a bully.
