I bought a yellow watchman goby about 3 months ago for a pistol shrimp I had and they paired up. Recently the goby left the pistol shrimp hole and joined my scissortail fish instead, I didn't think much about it. Now today the goby is swimming around everywhere. I do have a coral-banded shrimp thats pretty aggressive so it might have chased it out of the hole. Please tell me if you have had similar experience with watchman gobies. Here are all the pictures, the second to last one is the scissortail hole, the last one is where the goby used to live.
