hi everyone just had my koi pond over a yearand all my fish have been rather healthy until now, i bought 2 tancho and chagoi to put in the pond and within 3 days 1 tancho had like cotton wall on its side and the over formed a black eye, treated the pond with malachite, 1 tancho died and the other just dissapeared all of a suden i got on of my larger koi lost some of its fin tail and another with a raised patch of scales on its back, seems to be happening all over night, ive tested my water which was slightly high in ammonia in which i done a good water change, which made the levels perfect, just wondering if any one else had encountered similar problems many thanks jayj
