Keeping fish alive, should be the fist thing you should know how to do. I thought I did, but today I realize I don't. I used to keep my fish indoors (with A/C) and I was able to keep them alive for years. Recently I moved them outdoors, where all the protection they get is from a greenhouse I helped to built. Today, a few of my fish died because of the cold water!! I thought I new about keeping fish alive, but it is very different when they are outdoors, so I thought about sharing my experience: don't let fish in the cold!! when temperatures get under
60F you should start worring!! Today, we installed a quartz space heater, so we hope that is going to work out. I'll let you know what happens
