The Golden Shiners are aggressive and will likely feed heavily on the Fathead fry and most of the invertebrate population in a pond as well. They will eventually through attrition eliminate the Fatheads entirely from the pond. I have seen this many times here in MN. They may also eliminate many of the necessary zooplankton that your gamefish fry need to grow, and the gamfish fry as well.
I would be carefull if you put these in your pond so they don't upset the balance and end up as the only small fish you have.
The one bright spot (or not) is that they also eat their own fry too. So if you don't want or have trouble controling the natural reproduction in you pond the Goldies may slow or stop that and provide larger forage for your larger fish.
