Fathead minnows begin to lay eggs when water temperature reached about 68. We use wooden pallets and PVC pipe to minnows some structure to hatch under. We use a combination of fertilizers to promote growth and survival rates. We are never sure how well a minnow pond will produce, some ponds produce much better than others. Fathead minnows like pellet feed. Minnows are held two days(minimum) in vats prior to shipping, we can carry 100lbs per hold on the truck.
