I have 1 exception to the FHM rule, but it probably doesn't apply to panhandleguy, the first season of my pond I stocked FHM & GSH, by the next spring I never saw the FHM again but the GSH have thrived.
I think it was due to the 5.5 PH of the water, the chart I have shows the min. critical range of FHM at near 5.5, where the GSH min. is 4.5 .
