Im from central alabama an i stocked 1500 fathead minows 2000 BG/RES, first week of march .i put out some pallets for the fatheads to spawn under. dont think they really liked them

.but they did spawn all up an down the bank in shallow water an in the top of my sunken christmas tree tops. now i have a gazillion of them from .25 to 1.5 inches long swimming everwhere. every 6 days i have new fry an 2 days later a have bunch of new eggs. Did notice some BG spawing sites around the banks BG appear to be 2.5- 4 in long now. They were stocked from the state so they were small .75-1 inch.when stocked.
So you diffenllty got some thing going haywire. i dont know how far you live from pond but i go out around 8:30-9:00 pm with a bright flashlite an shine into the water at the banks an you can spot the fatheads an baby BG laying along the bank in 6-8in of water.
Good luck ;]
