Black Goldfish?

[L!NUS]

This might be a stupid question but what's with the black goldfish.

The reason I ask is that I have 2 in my 125 G pond, they seem to stick with each other more than with the 7 "gold" gold fish.

I bought like 20 feeder minnows for one of my turtles. He always misses a few. One happened to be greyish which is not unccomon. This fish grew way faster than all the rest of the survivors and soon enough it was clear that it wasn't a minnow at all because of its wiskers. Anyway, I decided to drop the 2" fella into my pond with the rest of my 3"-4" Goldfish(one which happened to be black).

Very quickly, like in a month or 2, the two black ones are at least an inch bigger than the rest of my goldfish. Why is this?

they may be a pair, i dont know enough about goldfish mating. or they could just recognize each other more.



genes can have many effects on the fish. they dont all have a single purpose. the genes that control color probably effect growth too.

electric blue jack dempseys arent just weak because of the in breeding but because the genes that control there coloration negatively effect there health.

the weather loach is smaller in its golden coloration then its natural one.

Thanks for the great info. That would be nice if they were a pair.

It has whiskers, right? It's koi, not goldfish. Goldfish do not sport "barbels". Can you post pics of your two black fish?

lol missed the wiskers, it being a different species may have a tiny bit to do with it.

I'll try to get some tomorrow.

I have pics from awhile ago of the regulars.

But I'm not sure, but I distinctly remember them all having Barbels.

Could the black ones just be plain old carp? http://aqualandpetsplus.com/Minnows,%20Carp%20II.htm

Mine look just like this, except smaller. This picture is a carp.

Goldfish are also carps actually hence why I used the term "koi" to distinctly distinguish them from the goldfish. All goldfish should not exhibit barbels unless they are hybrids between koi and goldfish by nature.

I can't see the blacks in your pic. The orange though are all hibunas (common goldfish) if they do not exhibit barbels. If suspected to be hybrids, then I would advise getting side view shots of them.

Black is a pretty unstable color in goldfish. If the fish in question have barbels, growing faster than the goldies, and the black color is getting better with age, you have Koi.

In my experience black goldfish will turn gold/red with age
