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.
And who says that the spec. “Sentang” traded actually are the same like in 2008 or 2009? They look nearly like the spec. “Sentang” from 2008/09 but this is no sign that there are from the same area.
I would be carefully to say it is spec. “Sentang”. Parosphromenus spec. “Sentang” are from Sentang and traded some years ago in a very large size. This is a sign that the area of Sentang get an infrastructure. Certainly these area used to become a land of plantations. That is the only one reason for constructing infrastructure on Sumatra. So one can suspect that in the area of Sentang can’t find Parosphromenus since three or four years after it became a land of plantations.
It is definitely a problem with kinds of Parosphromenus like this one that we can’t say what is is exactly. But I think that the original spec. “Sentang” from three or four years are extinct in nature!Christian Hinz
Some months too late but nevertheless a short response:
1. The area where Parosphromenus tweediei can find is only a area of plantations, almost no forests anymore. Still one can catch tweedieis there. I’am confused that licorice gouramies can survive in such area but it is possible. One factor could be the remaining peat.
2. In the north of Selangor I caught only three Betta livida in two houres. The small creek in the forest right side is dried up and the larger creek in the middle become fast flowing, so no lividas can found there. But Parosphromenus harvey can live in these creek good. However I think this is a natural situation. After more rain one can find there more Betta livida (this situation we had in April 2011).
3. The area of Northselangor was (is?) dry. One plantation burned! It seems to be that there was nor rain since weeks.All in all the situation is not significantly changed. It’s like one or two years ago.

Jit, at the end of July I will be in Malaysia again with two friends. We want to start our trip in Kuala Lumpur before driving through the country to the northeast. We are not Pat, but if you be interested we can meet us in Malaysia. Write me a short message if you want. Definitely is it also interesting for us to get to know malaysian friends of parosphromenus and our project!

Bernd and I caught many B. livida inside of the forest right of the creek from your picture number four.
I’ll see the actually situation in October. But the area of existing forest in north Selangor is very large and therefore I think that there are inside of the forests more places to caught Parosphromenus and Betta as we know.This are really good news! I’ll be a second time this year in Malaysia in October. When I have got time I want to go to the area of Parosphromenus tweediei again. Now I have a description how to find the three known locations for tweediei (but I think that Bernd and I caught at two of this places and find no tweediei).
Nevertheless we know now that all the six described Parosphromenus species of west Malaysia can be found.Yesterday I heard on the conference of EAC/AKL that the females (possibly of nagyi) were caught in Jemaluang. This village is located about 100km north of the known area of distribution of alfredi (east of Kota Tinggi in Mawai, Desaru and Sedili) and not too far remove from the occur of nagyi (which is quite large).

As Peter has already enumerated are there several different ways to breed Parosphromenus.
One is suitable for the extensive method (many plants) and others for the intensive breeding method (only a few plants, some even almost “sterile”). Each type can carry on their way to success with proper execution.
I prefer the way of Martin Hallmann: no or only a few plants, bubble-filter and only one breeding pair per aquarium. Also I have more leaves in the aquariums (two to three layers) and a swamp root. As caves I use ceramic or sometimes film-capsules.
What I try in recent times is to don’t take the young fish separately in plastic boxes but in a so-called “Gerdkasten” in the same aquarium. With a smaller number of young fish to 15 it will appear to work well.Christian Hinz
Possible is that the two species can find together because
1. the distribution area of Parosphromenus nagyi is larger than we definitely know
(not only from Cukai to Rompin, maybe in the deep south until to Kota Tinggi)
2. the alleged Parosphromenus alfredi and the nagyis are not from the typical location where we alfredi know from (Sedili), but from another biotope in the area of Kota TinggiHi Martin, I agree with Bennie that this are no deissneri. This are Parosphromenus with a round tail fin. Probably a bintan similar type. In question may come P. opallios, rubrimontis, alfredi, tweediei or also a unknown type from the not much known Sumatra or Borneo. A mix can not be exclude and I think it is probable. Even with a good picture, the assignment will be complicated or even impossible.

On the pictures of this link you can see a male of P. nagyi and allegedly alfredi (in my opinion this are not typical alfredis). They should caught supposedly together. Is that what you mean?

The undescribed forms from Malacca and Ayer Hitam are close to P. rubrimontis. There are a link between P. tweediei and P. harveyi. Initially were the forms from Ayer Hitam and Malacca falsely assigned to P. tweediei. But this two forms are for many years not in our aquaristic stock and the known habitats are extinct.
