Hi, I have about 7 small koi in a 30 gallon tank. They were fine when I first bought them 1 month ago. Recently, I found that there where white, long pigments on one of the koi and I immediately added salt to the tank and transfer that particular sick koi to another tank with salt. About a day later, I place him back when the pigments were gone. But now all the koi look very weak and were not as active as before. May I know if it's because of the salt? I haven't added any new fishes or ornaments lately.
