Diamond back and Golden Head together?

[Sonam]

We currently have a diamond back goby in a 32 gallon nano tank. We have a golden headed goby in a 125 gallon system.
We are considering moving the diamond back into the larger system so he has more sand to eat from.
Will they fight?

I have both in a 210 gallon, I've never once had a issue. The golden head was added first ( don't know if that mattered) Both fish have been together since 2017.
