Ok I buy a orange spotted goby and a candy cane pistol shrimp both are super cool. The pistol and goby never really meet up and seems the goby wants nothing to do with the pistol. So I’m at the LFS and I see a high fin banded goby small than the orange one he looks cool so I buy him. I put him in the tank and he finds the pistol in less than a day and they been under this rock for a week now. The high fin comes out by poking his head out and the orange spotted darts at him everytime. He is starting to tick me off because the high fin won’t even come out and now the pistol won’t either. Any suggestions on how to break the dominance of the larger goby? Isolate for a week or two then put back in or just give him away? Btw they in a 34 gallon Cube Reefer 170 ton of rock and the orange goby has his own spot that he stays in but perches himself on this rock waiting for the little guy to come out.
