GARDEN POND BLACK FISH

I seem to have an abundance of black fish in my pond. I only found them recently during the very bright weather. Is this just natural selection taking place or can I change them back to orange with a different diet?

Goldfish can have black markings and eventually produce black fish. It is a one-way process. Mrs PN says the only solution is remove the black ones and . . .

However finding all the black ones is likely to be impossible.

If you're unlucky most goldfish babies are black. If you only want to keep the gold (or other random) coloured ones you're going to be fishing out and throwing away quite a lot. Except you won't find them all.

T'internet suggests that baby goldfish are born black and usually change colour as they mature - assuming they receive the appropriate living conditions (sunlight and 'live' food).

Well they are about 7 inches long. So, no not tadpoles.

Aren’t you being a bit racist calling them black fish. Shirley they’re fish ‘of colour’.

The ones bred in the pond normally change to orange after a couple of years. At least, ours normally do.

Then the heron gets them!

Yes, they do all start off black ... but most of them stay black. "Usually" change colour is wildly over-optimistic.

The black goldfish are known as Ghost Koi.

All of ours eventually change to orange; the pond has been here with breeding goldfish for fifteen years. If they don't ever change colour, there is a chance they are hybrids.

Ghost Koi are hybrids - between "true" Koi and wild carp and we have some of them, too. Ours are silver/white/black and bright orange/red/black. They have dark rings around their eyes, which is where the "ghost" name comes from. They are different to goldfish in that they have a down turned mouth, as per the wild carp.

OK, fair enough. So in summary, experiences vary.

Angry

Thanks for all the replies. So feeding them carrots won't help it seems. Oh well, back to the fish shop we go. Heron notwithstanding!

They are fish and wonderful to have in a nearby pond, along with the frogs, waterboatmen and dragonflies.......
Do you really care about their colours?

If so, spend a couple of back breaking days in the blazing sun expanding the pond and then stock koi.
The herons will surely enjoy your efforts.

My aged mother has recently moved into a new property. It had a fish pond but due to a surfeit of grass snakes she decided to fill it in. It seems to have worked as the snakes have relocated to the village pond down the road. She's not anti snakes, by the way, but has one of those joke dogs that couldn't fight its way out of a paper bag, and so she was concerned that it would come out second best in a snake/pooch title fight. I like grass snakes, but can rather see her point of view, given how large the buggers were. Spotted one that wasn't much shy of 4ft.
