I hold all my tilapia stock in my basement...no heaters and only fed once or twice per week to maintain health, but to prevent growth. No heaters water temp is around 60 during the winter, but it is a finished, fully heated basement. Most of the vents are kept closed (except the wife's office) to keep the kids from using the computer or watching TV for hours on end.....hehehe
