Hi everyone, new to this site. Need some advice. Well basically I have an established pond at my current home it's about 800 gal. with about 10 fish ranging from 1 fingerling which is the newest fish he/she appeared when I was cleaning some leaves out of the Bio filter, must have gotten sucked up as a fry and survived prob. a 3" shubumpbkin. 1 lg koi prob. about 14"-4 lbs and the rest 4-6" fish. My problem is that I'm in NY 10941 nearing the beginning of winter. We are currently in contract w/ a new home, same area. We should be in the new place in the middle of January. What should I do w/ my fish? Buy a stock tank and take them in? I'm kinda lost. Thanks in advance......
