I have two species of P.nagyi.
One I am very certain of the origin of, – as it is one I got from Christian Hinz after returning from a trip to Malaysia.
But I am still a little confused, though. We talked about it at the recent meeting in the steering group.I just would like to confirm here, that picture number one is P.nagyi cherating form, and picture nr. two is P.nagyi kuantan form.
This last one is bought in a shop as wildcaughtAll fishes on the two photoes are not fully grown up males.
Helene is right: her pictures show two different forms (not species) of nagyi.
The first picture shows nagyi from around the location of Cherating. It is clearly recognizable by the fact that the coloured band in the caudal of the male is blue, or to say it in other words: the same colour as the coloured bands in dorsal and anal.
The second and the third pictures show a nagyi from around the location of Kuantan (which is more widely distributed), and it is clearly recognizable by the fact that the colour of the band in the caudal is white (whereas the bands in dorsal and anal are blue).The Kuantan-form is the “classical” one, and is to be recognized in some other features, too. For instance: the caudal appears to be very short indeed because of the rather long overstanding spines. This is less the case in Cherating. But this feature is not clearly to be seen in these photos.
The first who caught this species was Peter Nagy de Felsö Gör from Salzburg, and Dietrich Schaller (Munich) described the species some years later using his name. It was the Kuantan-form. Only some years later Martin Hallmann (Weinheim) detected the Cherating-form and its aberrant features.
We don’t know whether these differences that are always clearly to be seen in live fish indicate subspecies or some less important difference only. In any case: One should not mingle those forms! Keep them separate!
Hello Helene,
Peter explained it completely right.
The first ones are nagyi from Cherating and the second form is the one from Kuantan.
This nagyi-form has a larger distribution area than the Cherating-form and lives more south.Here is a picture how the nagyis from Cherating, which you got from me, will look in breeding colours.
You can see there the light-blue band in the claudal of the male. One cannot find at the Kuantan-nagyis.Additionally, I added a photo of the location where Bernd and I caught this species.
Hello Christian.
Good to hear from you. Yes, the nagyi in my first image is actually the smallest of the 3 males which came from you.
The two other males has been very productive fathers, and I have now a small (luxury) problem with around 30-40 offspring growing up, some of which already with own offspring. So its has been very succesfull with those four fish I recieved from you in Hannover.Hello, Helene,
I hope it’s ok when I use your thread to show my very first paros 🙂 ………. It’s P. nagyi “Pekan Nenasi” – so I think it fits quite well into this thread.
I got them yesterday, they were bred by Thorsten Kolb and Anne Pähler – whom I thank again for the wonderful fishes!
The photo (I hope I succeed in uploading it …) shows the fishes exploring their new home, the male on the left.
Bartian noticed – looking at the same photo in the IGL-Forum – that my male has no colours in the caudal fin. And he is right – I looked through all the photos I took today – the male never shows any colour in the caudale.
Not even here:
What do you think??
I think you and Bartian are right, – theres not much colour in the caudal fin.
Are there many fish in the tank together ? The only time I have experienced males not to show full colour is if there are many fish or many males, then some of the males are kind of sub-dominant and show less colour.
But yours is apparantly the most dominant ?This is a striking case, a nagyi-male without any colours in the caudal. I have not heared or seen anything similar before. I shall ask some of our specialists of this species whether this has been observed before. Normally the colouration of the caudal in the males of the known varieties of nagyi (Kuantan, Cherating, Pekan Nenasi and even the somewhat strange fish from Kota Tinggi) are clear and obvious.
Stefanie: Did you observe this with relatives of that individual, too? Or is it a singular phenomenon?
