Goldfish tails

[Cobreth]

I have two Black Moor goldfish in my tank. Both were bought at the same time out of the same tank, but one fish has a tail that is connected at the top, and the other has one that isn't. So one fish has a tail that looks like a triangle missing the 3rd side, and the other looks like he has two tails.



Does anyone know why this is?

They were like that when I bought 'em.


I don't know how they're supposed to be. Do you think I have a "mutt" or something?

I believe its a genetic thing. I'm not a goldfish person though so maybe someone with experience with them will chime in.

Hello Cobreth, like Hound said it is only genetic thing. There is nothing wrong with either of your fish, unless you plan on entering your fish in a contest then the one with the split fins will do better.

Here are a couple of links to check out what their standards are. There is also a cool on variety called Tosakins.

I went to Petsmart today to look at their Black Moors and they all had split tails. I thought the split tail was the mutated one.


But, meh.. I like the joined tail.
