Pond Boss Forums INTRO Questions & Observations Where do FH minnows come from?

Dr. R: the lowly, vulnerable fathead minnow has a few tricks up its sleeve, just as Mother Nature usually does. Probably the most impressive tidbit about fathead minnows is that they can probably tolerate the lowest dissolved oxygen in water compared to any other freshwater fish we commonly discuss. The D.O. can almost be too low to measure, and they are doing just fine. Thus, they can survive in marginal waters that will not support other fishes, and always have a "refuge." In the northern great plains, they persist in wetlands with no other fish. During high water times, they various wetlands connect to lakes, providing a supply of fatheads to the lakes.
