    also from Burma, I am sorely tempted to call it Danio sp. ‘hieroglyph’ on account of the gold pattern on their flanks.


    *updated pix*

    hereby the specimens I received from Tin Win back in 2005, hence the label TW03

    Dont' seem that drab to me. I like the yellow and blue color combination.

    What kind of substrate are you using? The reflection on the belly seems to be quite strong..

    Cheers,
    I have dwarf cichlids in my tanks! Do you?

    under normal lighting the blue/yellow combination is not obvious, plus it is very small so you can hardly see, especially if you wear bifocal like me.

    i think the best thing about these fish is even though they look a dainty and fragile fish, ive found they can be kept with medium sized fish with no problems.
    to get the best out of them is to have direct sunlight the colours they show are truly beautiful.

    Choy,

    Why don't you use a darker background? White has a tendency to be underexposed as in this case, judging from the styrofoam board.

    I need a shallow dish that I can dispose of after use. just at that point where you have freshly frozen fishes, isn't a really good time to find a good implement for holding dead fish in shallow water

    my wife objects to the use of her teflon coated pans, so there

    for those looking for this fish, Eco Culture has a tankful labeled as Danio cf. choprai.

    Re: one more undescribed danionin from Burma - Danio sp. 'TW03'

    this fish just described!


    Danio aesculapii, a new species of Danio from south-western Myanmar (Teleostei: Cyprinidae)

    Danio aesculapii, new species, is described from small rivers on the western slope of the Rakhine Yoma in south-western Myanmar. It is superficially similar to D. choprae from northern Myanmar in having a series of vertical bars anteriorly on the side, but differs from it and other species of Danio in having six instead of seven or more branched dorsal-fin rays, and from all other species of Danio except D. erythromicron and D. kerri in having 12 instead of 10 or 14 circumpeduncular scale rows.

    Re: one more undescribed danionin from Burma - Danio sp. 'TW03'

    hi choy mate, i think i'm still the only guy to breed them in the UK unless Pete Cottle has done them.
    i'm sure it's to do with the water where i live which is very soft compared to pete's water which is very hard.
    it's a fish that never took of over here because i thinkthat to most people it looks drab, but i've seen the colours that they can show, very subtle but beautiful.
    if i can find a few pics of the youngsters i'll put them up mate.

    mick, do you think the two specimens in the dead fish pix represents a male and female?

    yes mate, infact both the pics show pairs.
    the females have a longer thinner bars on the flanks than the males.
