So last week in the UK we had our big freeze and wasnt able to check on the pond until monday. I noticed therr was a few fish missing but thought they may have been in hiding or something. Yesterday i went down and there was one of my GF dead on the bottom, i put it down to the cold weather and removed him. Ive gone down this morning and saw another on the bottom, i scooped him up and there was a frog attached to him! I had to physically prise the frog off, thankfully the tench was alive and i removed the frog from the pond.\n\nIs there anything i can do to stop oi again? Also im not saying all of them were from frogs as maybe the cold spell played a part, ive lost 6 alltogether just this week.
