The usual reason scales turn black is ammonia burns. Have you checked your ammonia level?

stroppy said:water changes will help lower ammonia try changing 10% for a few days and cut down on the amount you are feeding the fish untill it settles down, spawning just let it happen ..make sure your mop is near the top of the pond ... the change in weather may have bought on an early spawn its warmed up a bit here but my pond is still only just above 50 Celsius 10 Fahrenheit how warm is your pond ?
dont forget to add decoler when adding new water
if the fish are spawning they wont be that bothered about food anyway ...also if you dont feed they will eat more of the eggs :0)
my thoughts exactly.....i have a koi thats black speckled spot numbers have increased over the last couple years. but shes always had a huge number of them.fishin4cars said:I'm intrested in hearing what others say on this, That really to me just looks like color pattern that is appearing to display stronger, I don't see any tell tell signs on the fins of ammonia, the water changes will for sure only help the pond so no harm there at all, To me the fish looks very healthy and in good shape.

fishin4cars said:look at that pic and at the fins of the fish, That fish has had some kind of serious reaction, the pic of your fish the fins are clean and fully intact with no frays tears or red streaks.
I know Koi will change and can add black over time on some color variations, Comets normally don't add black they usually lose if if anything which is what makes this more intresting.
