I have a 95 gal reef tank setup. Currently houses a Golden Headed sleeper goby. I would like to add another goby to the tank. I was thinking of adding a Yellow Watchman goby and and a Green coral goby or Yellow Clown goby. Would these new additions be compatible with the Sleeper goby already in my tank or would there be a problem. Anyone have any experience with housing these fish in the same tank? Thanks
