Up until recently my pond consisted of a single koi, a single catfish and a handful of goldfish. I went outside to feed the fish yesterday and only the koi and catfish were there. There were no signs of foul play so I’m not sure what happened. This happened once before, though. It was a mystery at that time, too. After the first time, we added some hiding spots to the pond, but evidently it wasn’t enough. I guess some sort of wild animal got into the pond, but I don’t have a guess as to the species.
We’re going to add more hiding spots and wait a few weeks before restocking.
