A Dutch shop currently has a lot of P. bintan-like fish, mixed with some sumatranus. They bought them as P. filamentosus, which doesn’t make sense at all looking at the fact there is not a single one bearing a filament. Also, these come from Sumatra, filamentosus from Borneo.
They didn’t show much colour, so it was impossible to tell exactly what species it is. Based on the fact there are bintan-like forms near sumatranus‘ range and the blue caudal band I think it is one of those Sumatran bintan-forms.
I’ll update this when I have more information.
January 20, 2014 at 9:44 pm #6110Peter FinkeParticipantBartian, that is exciting news … i f… the fish are really P. sumatranus. But I doubt it. Even sumatranus have a very small filament in the caudal fin, in both sexes (1 mm, but clearly to be seen). Additionally, the wohle colouring and the stripes on the body are somewhat different, especially the lowest faints into a very small streak. At last, most fish are slimmer than bintan-like forms, a bit reminding at parvulus and ornaticauda. (There are broader types however, too).
The fish you describe is certainly not filamentosus but probably a bintan-like form from Sumatra. But why do you guess it’s sumatranus? This should be clearly recognizable by the structure and colours. O doubt that, not in principle, but because of your description.If they are sumatranus, then: buy! Buy! We lost nearly all of them in our stocks! They are most interesting: with head-up display steeper than ornaticauda!
January 20, 2014 at 10:11 pm #6111bartianParticipantThey are indeed slimmer than the other paros (some even like parvulus, but most are higher built), they have somewhat different stripes, and their colouration is really different. They have dark reddish fins with a distinct black spot in the dorsal fin.
What species other than sumatranus has a conspicious black dorsal spot? I only know it from sumatranus and allani, of which the latter seems very improbable.
If they are that rare nowadays I’ll get me some. I couldn’t clearly distinguish female sumatranus, do they have colour in their fins or are they clear like bintan?
January 20, 2014 at 11:03 pm #6112helene schoubyeKeymasterIf in a dutch shop, theres a good chance they will appear in Denmark as well, I will certainly keep a look out for them.
Your describtion in your last post gives hope that it could be sumatranus indeed as far as I know.
I had sumatranus for a period, unfortunately no more.Do you have any idea which importer ?
January 20, 2014 at 11:26 pm #6113bartianParticipantThey’re from an Indonesian exporter, imported by the shop itself. No Ruinemans, so very small chance you’ll see them, I guess.
January 20, 2014 at 11:33 pm #6114helene schoubyeKeymasterNo, Ruinemans would be better 🙂 you are right about that – they often end up in Copenhagen too, but you never know.
I will keep an eye out for any new paros in townJanuary 21, 2014 at 12:22 am #6115bartianParticipantI just got sent this: https://www.youtube.com/watch?v=2yLpQO6GHdM&feature=youtu.be
Right in the beginning and just after halfway there are some supposed sumatranus.
January 21, 2014 at 12:23 pm #6116Peter FinkeParticipantRight, I agree. The last fish swimming from the right to the left is probably a sumatranus male. The others are not as clear as this to be seen.
Females in principle have the same black dot at the end of the dorsal, but often it is subdued.This private import might be a mix, that’s a problem. Nevertheless: P. sumatranus is very rarely traded. You should definitely buy the individuals that are most clearly to be recognized.
And since it is a private import, Helene’s hope to meet them in Kopenhagen (or ours in Germany) is not very likely. Sorry to say.
February 4, 2014 at 9:34 pm #6162bartianParticipantI got me some new fish yesterday:
No doubt possible about this being sumatranus. I got seven of them, but I found it quite difficult to distinguish female sumatranus in a tank with 200 scared Parosphromenus. I think I have two or three females. While looking for females, I also found this:
It lacks the blue distal band in the caudal fin, which bintan normally do possess. Instead, it shows a reddish band near the caudal peduncle (it is much more intense and visible in reality). The bintan-forms I know (and the other ones in the tank) do not show that band when under stress. Also, it’s shape and size is different from the bintan I know, and it’s unpaired fins are much more rounded than my other paros’ fins (note the very short ventral fins!). I think this is interesting, because I have three types of bintan, and this one looks really different. I caught two similar looking females, so hopefully more will be visible soon.Please don’t mind the cyanobacteria and the fungus on the wood, I’m aware of it and hate it! It seems I have a nice, very invasive and plant-killing strain of cyanobacteria resistant to pesticide.
February 24, 2014 at 11:15 pm #6254Stefanie RickParticipantBartian, is this the one of the fish you recently bought which you mentioned today in the gunawani-thread? The stouter one with more rounded fins?
It is a pity that nobody looked at your pictures or answered your last post. It would be interesting what the experts think – of your sumatranus and of this unknown species/form.
February 24, 2014 at 11:31 pm #6255bartianParticipantIt’s that fish indeed. It now has more colour, and a very thin blue band in the caudal is visible at times.
February 24, 2014 at 11:46 pm #6256Stefanie RickParticipantMaybe you could post another photo, showing this stronger colouration?
February 24, 2014 at 11:51 pm #6257bartianParticipantI tried making some, but it is afraid of my phone. It always darts away when I try to make a picture, very annoying.
May 26, 2014 at 4:25 pm #6593Ed PrustParticipantI got four of these too. Same shop, same batch i think.
My tank has a lot of hiding space so i havent been able to take a pic yet. Also i have dim lighting.
I probably have at least one male.
First order of business: getting them big and healthy.
Tankwater: pH=6.5, 70 MicrosiemensMay 26, 2014 at 7:39 pm #6594Peter FinkeParticipantBartian, I could not reply earlier. The male fish in photo 2836 is without any doubt a P. sumatranus. Even the small filament in the end of the caudal is well to be seen.
The other fish in the next picture is – I am afraid – definitely no sumatranus. I cannot say which species it is; it resembles a bit a poorly coloured anjunganensis, but it maybe quite a different form, even a hintherto unknown. I suppose, it’s a male too.
It is very rare that shops mix different species. They probably haven’t done this in the Netherlands but they will have received the fish in a mixed bag. This is rare, too, but it happens. You should try to get some sumatranus-females, too. P. sumatranus is one of the most interesting species we know, since it is coloured in the bintan-like manner, but displays head-up similar to ornaticauda. Sometimes, it will even stand still more upright, really in an angle of 90% (defiitely vertical)!
It would be of great importance to build-up a new stock. Several years ago, Karen Koomans from Nieuwe Pekela ha a big stock, but all are lost in the meantime.
