I've recently had to change my pond due to a leak, when I removed the fish I found 3 extra small orange Fish with black dots on there back just behind the dorsal fin all the same.there about 3" long and look healthy but are a completely different colour to the gold fish and look more like the golden orf, I had a lot of activity last year ( fish chasing each other) and I've noticed the same activity today but the water has turned milky. It was clean water that I added yesterday what do you think it is, the water had turned milky in the leaking pool 2 days ago but previously was crystal clear. Any help would be greatly appreciated
