The kois are turning red/orange and the medium sized one looks like his head is flaking, and the big one is staying near the bottom and does seem to gasp sometimes.

The Pleco, however, didn't seem to have anything wrong with him, so I was expecting him to be ok

No white spots, but they do swim a bit funny, the big Koi seems like it tries to swim up but keeps sinking?

Maybe if I took pictures/video?
