Hello recently my pond was visited by Herons and they ate all my fish, I i got more fish and net covered it. Re-stocked with fish 20 goldfish and 17 black goldfish? I know g/fish start life black but these fish are 3 to 4 inches long now, The goldfish are eating all i put in the pond but the black fish have not eaten at all since i put them in 8 days ago Any ideas why?
I wouldn't worry about the fish not eating,once your pond is up and running you do not actually need to feed your fish there'll be enough natural food in it the food you add is only to promote rapid growth and enhance the colour of the fish. As to the black fish I've got a goldie in the pond about 6" which was bred in the pond and has never bothered changing colour but 17 that size that haven't changed seems unusuall, as woofgang says check with the guy who sold them to find out just what they are
My pond goldfish produced a lot of black baby fish after having a bit of business. They first turned stripey before eventually going all gold.
Feeding in Summer is not necessary, there are lots of insects landing on the surface of the pond that they gobble up. Also, any wasps or bluebottles that I swat in the house I put in the pond and the fish eat them, though only the biggest fish can manage the hornets that I terminate.
