A friend stocked GHS, FHM and Gambusia in a couple of his ponds. The only minnows that we continually see are the Gams. They went from less than a 100 in the pond to 1,000's by Fall.

DIED put 9 (yep nine) Gams in his pond and those 9 turned into thousands. From those thousands I put in about 50 Gams into my pond and I have schools of Gams that I see are huge.
