Hi,\nI’m in zone 6b and have winterized my 1500 gallon pond. I’m running a bubbler for oxygen. One of my koi babies from this year is trying to get into the koi castle with the others but can’t seem to make his way in. He’s can’t find the openings. Also, when I took the netting off to remove leaves a giant frog jumped in. There are really no places to hibernate as it has a rubber lining. Should I attempt to net out the frog and move my koi or leave them to nature. My last pond was away from my house and I didn’t witness any of the daily struggles.
