better served adding 3500-4000 bullhead minnows $350-400 there is plenty of cover,
Based on my assumption you are talking about fathead minnows that could be called bullhead or bull minnows by Zetts fish farm. True bull minnows are a form of topminnow (Fundulus grandis), also known as gulf killifish, mudminnows, mudfish. Using the term bullheads could confuse PBoss readers who would think these are "bullhead catfish" aka black, brown, and yellow bullheads. For fatheads or "bull topminnow" to have a low breeding population and survive long term in a naturalized pond there needs to be abundant submerged vegetation. Abundant as in almost too much vegetation to easily and commonly fish from shore. Usually manmade and tree branch cover as fish structure is not abundant enough and dense enough as good cover protection for fatheads(FHM) and most minnow species. If you are looking for a soft fin forage fish that is more likely to survive with some annual breeders in your ponds, consider using the forage fish money budget by adding adult golden shiners (3"-5").
Important note. If you want to use tilapia to provide good forage for the predators then make sure the TP are mixed sex and not primarily male fish. Some TP sellers provide food fish grown tilapia that are almost exclusively males who grow faster and larger than the female TP. Thus with all male TP one gets no offspring.
