Diamond and Orange Spot gobies compatible?

[90GalFOWLR]

Would a Diamond Goby and a Orange Spotted Sleeper Goby be compatible in the same tank. I have the orange spot in there now because I really liked the Diamond goby but after a few months havent been able to locate one local.

Now I have found one... Would they work out together?
