Diamond Watchman Goby Compatibility with Blennies

[Arcane Corals]

I have a 135 gallon display that I have a rather large Diamond Watchman Goby in. He's definitely focused on the sand bed. Would there be an issue with adding a blenny?

If compatibility isn't an issue, what type of blenny would y'all recommend for this tank?

We have a Bicolor in my 25 gallon lagoon that is the best fish ever. Sleeps in a shell, super personable...he's the main reason I want one in the bigger tank.

I like a BiColor goby but the match is not guaranteed to work, according to the internet?
