I kept some minners I bought for fishing about a month ago. Had about 7-8 dozen left over so I put them in my big water cooler (10 gal) that I use for my minner bucket and put some of that blue stuff in it to keep em alive. They are doing good! they froze one time solid, and I crank up the air bubbler every other day or so. My question is,,,,now they have turned blue! not sure if that is good or bad?? anyone fished with blue minners before?
