Clown Goby with Clownfish?

[Blocker620]

Hey everyone, I have a 13 gallon tank with a Mocha Clownfish, 2 corals, and snails. I just wanted to know if I would be able to put a clown goby in or would it start causing problems. Thanks.

Not sure I would recommend any more fish at all. Small tank and clowns can be territorial
