    Ah, ok. Here is one from Sanggau:

    http://www.kolumbus.fi/vuorela.antti/sanggau__page_2.htm

     Oh, totally forgot Antti’s pages. I figured they are not even online anymore. Have to read with time.

    That’s why I called it Pangio doriae “gold”! Laugh

    Nice!

    Are there any reason why you choose the name P. cf. anguillaris? For me, these loaches are P. anguillaris, without cf.

    Hi, i can’t name any clear differences in appearance, but i’m fairly sure my specimens are not from Borneo or Sumatra. I remember in recent scientific literature it’s mentioned that P. anguillaris is probably restricted only to those areas, and other specimens are yet to be new species. I’m not aware of any photos of (live or fresh) P. anguillaris from Borneo. I think also in scientific literature it’s all from SEA mainland? cf. may be unnecessary, but i like to use it if not sure ;)

     

    Does anybody have a thought why these are imported as P. piperata?

     

    I’ve here a group of another form of the anguillaris, it’s an unspotted and maybe undescribed “variant”.

    They are very nice! I’m pretty sure these will be described as new sometime in the future. Here’s a good photo and data of specimen that’s very close to your’s (maybe you have come up to this already)

    Hi Thomas and all!

     

    And sorry Thomas for intruding into your topic.

     

    Here’s some photos of P. doriae and P. cf. anguillaris

     

    P. doriae male (i think this darker form is true P. doriae because of the cheek scales)

    P-doriae-male-2.jpg

    White form of the P. doriae? (female). This specimen was not this white when i got it.

    P. cf. anguillaris female and P. doriae male

    P-cf-anguillaris-female-P-doriae-male.jpg

    P. cf. anguillaris females (gravid female on top)

    P-cf-anguillaris-female-gravid.jpg

    P. cf. anguillaris male

    P-cf-anguillaris-male.jpg

    P. cf. anguillaris from Singapore wholesaler, but think these originate from Thailand?

    P-cf-anguillaris.jpg

     

    Bigger photos here

     

    These two species behavior is quite different, eg P. cf. anguillaris is much more social and day active.

     

    I think some P. oblonga forms also behave different from other. Have you noticed this with different forms of same looking eel-loaches?

     

    Hope you can get some sense of my english :)

    Two Yunnanilus familiar from aquarium trade:

    Y. brevis is now Petruichthys brevis and Y. cruciatus is Micronemacheilus cruciatus

     

    Again, if i’m reading the paper correctly, some of the old Yunnanilus is now split also to Eonemachilus

    It seems Homaloptera is now split to BalitoropsisHomaloptera, Homalopteroides, Homalopterula

     

    eg. Balitoropsis zollingeriHomalopteroides smithiHomalopteroides tweediei, Homalopterula ripleyi

     

    This paper surely keeps you busy for a long time ;)

    Finally there is a color picture of the real Pangio kuhlii  !

    I came across the following information from Aquarium Atlas:

    First imported 1909 by Vereinigten Zierfischzuechtereien, Berlin Conradshoehe, Germany.

    The information is for Pangio kuhlii, but apparently the imported species is actually P. semicincta

    Agreed, great info in this thread. Is this sp. PAN04 Thomas?

    Sorry for taking this topic to sideways, but to my eyes PAN04 lighter and darker forms isn’t the same species.

    I think i can see nasal barbels on the lighter form and only tubes on the darker form. Pigment (small dark dots) are more clearly divided from the lateral line on the lighter form (excluding last caudal part). Also the darker form has heavily pigmented pectoral fins, but on the lighter form the fins are very clear.

    @stefan said:
    Thanks a million!! This is more than enough. So as the taxa currently stand I can understand it as oblonga with a forked caudal and pangia with a rounded one?

    To be exact, as defined by above  (cause my english is not the best):

    P. pangia caudal fin is rounded

    P. oblonga caudal fin is truncate or hardly emarginate

    “I believe P. pangia caudal is slightly rounded and P. oblonga has truncate or slightly forked”

     

    That might help a lot. Do you have a source for that information?

     

    P. pangia
    Hamilton, 1822 : The caudal fin is small and rounded (p.355)
    M´Clelland, 1839 : The fins are round and small (p.435), drawing confirms this (fig.5 plate LI)
    Cuvier and Valenciennes, 1846 : La caudale est arrondie – The caudal is rounded (p.76)
    Blyth, 1860 : This has small fins and a round tail ; but certain Indonesian species affined to it have a forked tail (p.169)
    Day, 1889 : Drawing (fig.81 on page 222)

    P. oblonga
    Bleeker, 1862 (on 2012 translation) : caudal fin expanded, truncate or hardly emarginate (p.84), drawing comfirms this (p.83)

    …have to go to work now – i’ll find more refs if you need to ;)

    Many pictures on web shows P. oblonga, alltough it says P. pangia.

    And not to make things too simple, i remember it’s said that there’s probably more than one species in the group defined as P. oblonga.

    Fraser-Brunner, 1940. On some fishes of the genus Acanthophthalmus… :

    During the last few years certain striped loaches of the genus Acanthophthalmus Bleeker have been very popular among aquarium-keepers, and i have had an oppornity of examing a number of specimens, both in life and after preservation. These were all imported and sold under the name Acanthophthalmus kuhli, but examination left no doubt in my mind that several species weree represented among then.

    Then there’s a picture of A. semicinctus pattern on next page. So P. semicincta has been imported to U.S. at least in the 1930s, possibly even in the 1920s. I believe Europe is no exception.

    I believe P. pangia caudal is slightly rounded and P. oblonga has truncate or slightly forked
