Newsletter 112 distributed in November of 2013 noted that a number of “Paro” species were commercially offered for sale in both Europe and North America. Species included both P. Tweediei and P. Nagyi as well as several others. I unsuccessfully chased the P. Tweediei for several weeks both at the wholesale and retail level. There appeared to be but one imported shipment to North America. I was only able to see an image of a single and that fish turned out to be a wild betta. While personally disappointed in not acquiring this species, I was pleased to hear several weeks later that the P. Tweediei did appear and was authenticated in Europe. Parosphromenus Nagyi is another story here in North America. This species has become readily available and the Asian source reportedly comes from AQUACULTURE TECHNOLOGIES(Patrick Yap). I am happy to report I should have a small group of these fish in my own tanks to celebrate the New Year. I pray that we do not get extreme cold weather that will delay the arrival.
This brings up a question with regard to P. Nagyi. On the species page two sub-groups are identified – P. nagyi ‘Cherating’ and P. nagyi ‘Kuantan’. However, for some time Stefanie Rick has been providing us with some magnificent images of what she refers to as P. nagyi ‘Pekan nenasi’. While several of her images are included at the bottom of the species page there doesn’t appear to be any further description of this group. Is it possible to provide more of a description of this beautiful fish and add it to the species description?Hello, Bill,
even though I am surely not the most qualified person to answer your question, I will try to give you a first answer by translating the P. nagyi-part of the new paro-book by Finke and Hallmann. I hope the authors will excuse possible ups and downs of my translation ……… :unsure:
Especially the forms of [i]P. nagyi from southern localities show a curiosity: The rim of the caudal is not pigmented but transparent. In the local forms from Kuantan and Pekan Nenasi the turquoise seam of the caudal fin is not located at the fringe of the caudal – which is different from all other species. Males in nuptial colouration seem to pretend to have shorter fins – an alleged contradiction to the accentuation of size and brightness of fins in paros.
So, we know two differentiable varieties : First, P. nagyi „Kuantan“, P. nagyi „Pekan Nenasi“ and further localities south of the terra typica, with white bands in the caudal fin and a prominent spot at the hind base of the dorsal fin.
Second, P. nagyi „Cherating“ with regular turquoise bands in all unpaired fins. The transparent fin margins/projecting fin rays, respectively, are, by far, not as distinctive as in the other forms. Thus, the caudal seems to be larger in P. nagyi „Cherating“.[/i]Maybe this can be a first step to explain the form “Pekan Nenasi”.
Here the transparent margin of the caudal in “Pekan Nenasi” is very well to be seen:
That explanation helps a lot. I assume you obtained your ‘Pekan nenasi’ from a local breeder rather than the commercial shops? It will be interesting to see what my colony will look like when they arrive. I am told mine will be between 2.5cm & 3.0cm in size, which leads me to believe they should be adults.
Yes, I got mine from a breeder here in Germany.
If yours are announced to be about 2,5 to 3,0 cm I supppose they will be not quite adult yet. Mine (now about 1,5 years old) measure about 3,5 cm.
It would be great if you could show some photos of your nagyi after they have acclimated to their new home.
Dear Bill, you are fully right in pointing out that my species description in the species section needs to be supplemented as P. nagyi forma Pekan Nenasi is concerned. I shall do it as soon as possible. In the meantime, Stefanie has given a very good translation of the text in our book.
A Merry Christmas, Peter
