They eat algea, algea, and more algea(including blue-green algea). They are an excelent forrage fish because they spawn like mad and have alot more meat on thier bones than most other forrage fish(I,ve heard up to 4 times as much protien per weight than shad or shiners). They also make a great aquacultre fish because they grow fast on on low protien feed and make nice fillets. The problem with them is that they die when the water temp gets down to the mid 50's and they're an exotic species so you need a permit to stock them. If you want more detailed information you can look on a web site on raising them for aquacultre.
