well i have a green clown with a yellow clown with a scissor tail and a firefish and they gets along just fine but then again I have been told I'm lucky. Sure not all gobys can mesh. But under the right tank settings its plausible. its always a gamble with them also. in my tank they get on just fine. but say in your tank it could be an endless turf war. So I say MONITOR if you do it. I was worried when I did the Green and yellow clowns. But they do just fine for me. I don't know if I was any help but best of luck to you if you do get them...
