I'm getting (a) pinecone fish and soon flashlight fish, and I really want to know if it's safe to put cleaner shrimp I. With them. I'm sure it's fine while they're small, but both aren't your standard reef fish. Even though they live in reefs, I don't know if cleaner shrimp are out and working at night, and if not, those fish might not be familiar with their work, so I'm worried about when they get big enough to make a meal of a shrimp.
