Yesterday I added 4 koi to the pond, these are young koi, today I go to the pond, I see one young one at the edge of the pond, to me I thought he was death but I splash the water a bit and there he runs off, another one I thought was dead was at the bottom, I grab him with the net, nope still alive so I let him go. They seem to be very sluggish for some reason, it is because they are not used to this kind of environment, or water quality? Because I have already 3 koi which are larger than them, and around 5-6 goldfish, the previously placed Koi & Goldfish show no signs of lethargy or being immobile, but these guys it's like they're depressed, they constantly go to the edge of the pond, trying to escape or something else.
But if it is a water quality issue how come the other Koi/Goldfish are active and running around like crazy? Or is it just that it takes time for them to get used to it? Not really sure, I have one of those submersible pumps which aerates it, but I am not sure that aeration is the problem?
