Hi,

and some details of the young male:

There are really nice shots! Thank you very much!

And I see the male is not corrupted...in my line the males have some black in the anal fin

No deeper knowledge; the conjecture (coming from someone else on this forum who would hopefully comment) is that this is corruption as the result of inbreeding.

But if multiple strains exist in nature, then indeed it may be simply that the fish that was originally imported to the US already had this feature.

Did you see males with black in Europe? If yes, this would argue for multiple strains.

[Dirk G.]

I only know from other German internet sources, that some people have males with black in the fin, some not. But I do not know, how many times peacock gudgeons have been imported to Germany...and if it is normal in nature......

Interesting discussion.

The first lot of peacocks that came into Australia
where males with red edge on the anal fin and females with black.

Then they where taken of the import list and over time all the males
we had where showing black on the anal fin.

In the last few years we have been able to import them again
and we now have males with the red edge on the anal fin again so there may be something to inbreeding and males developing the black edging on the anal fin like the females.

Just a thought, but since this has now been verified on 3 continents, I do not think it to be a question of "inbreeding" but rather that in nature perhaps a male with black on the anal fin is not a females first choice? In the an aquarium setting she has to take what you can get. Also, the black may be a dominant (or more dominant) gene, perhaps associated with some other characteristic (color, behavior, etc.). Just a thought.

Those "corrupted" ones Mike refers to are mine. When Gary visited me he showed me this as I had never noticed it before. He claimed that it was an aquarium strain phenomenon and that the fish in nature did not show this confusion. But that's to be expected for any fish that is easy to breed and hasn't had the attentions and awareness given to the purity of other species.
Perhaps we can be on the lookout for F0 ocellicauda.

Any further thoughts on this??
