I just bought them 2 days ago and the first day they were hiding but weren't with eachother. My pistol shrimp was in a rock and my goby was under one. i think its called a barbershop goby? Anyway.. i found them that night and now there nowhere to be found -_- i have a foxface Hippo tang Percula clownfish 3 little damsels naso tang 2 starfish and a different goby (orange spotted watchman?) but the guy said they'll be fine together. Any suggestions?
