    I’m confused! These were sold as sewellia elongata, I don’t think so. Look more like s. speciosa, but???? What are they???

    Doing some searching and ran across this again. They look like sp. 1 to me.

    I’ll get some better shots when they settle in.

    Hi Jim,
    they look exactly like my fish!
    Apparently they are offered as S. elongata.
    But it is very hard to say, maybe it’s the real S. breviventralis but who knows?
    S. speciosa is ruled out because the body shape and the markings do not match.

    Hi Menu, How are yours doing? Have you seen them eat anything that you’ve offered? These are in a bare quarantine tank that has lots of diatoms on the glass and they’re furiosly grazing!

    Lovely fish Jim and Menu. We need a copy of Freyhof (2000)!

    I have the new Sewellia spp. now since the beginning of November and they doing very well!
    They ate from the first day, frozen Artemia shrimp, Daphnia, tiny Bloodworns and even Shripsticks are a good choice.
    They love a stronger flow and need more oxygen, such as for example S. lineolata needs!

    it’s the species first sold as s. breviventralis. after some discussions with J. Freyhof we considered it to be s. elongata. in the article of -amazonas-magazin mai/june, kamphol presented s. elongata with yellow bordered fins as s. elongata, this one should be another s. sp.
    weltenbummler near by had the first youngsters – presented at loaches, mine cam a week later and are adult now. very fast growers for sewellia, faster than s. sp “spotted”.
    the paper comes tomorrow, Matt. but it doesn’t help to a solution.
    i may present all species known with pics tomorrow too?
    cheers Charles

    ok then
    first species to show was presented in march 2009 by Glaser as s. breviventralis and looked like this

    I thougt it couldn’t be s breviventralis but elongata


    and what about the specimen with stronger markings coming with the same shipment, looking like this?

    seemed the same species to me

    in amazonas-magazine the first is presented as s. sp aff. elongata, the second as s. sp (not s. breviventralis for shure)
    the youngsters of s sp – “not breviventralis” if we follow that classification – looked like this in autum 2009

    they developed a clear pattern to broken stripes like this

    and look like this before becoming s. sp aff elongata with the strong markings of the second type shown above

    which brings us back to the question if Menu`s/Jim’s species is an subadult s sp aff elongata?

    after some time I realised that there is a second species in the second shipment
    could it be s. breviventralis?

    they didn’t spawn as far as I know

    for more pics see this

    some pics of speciosa
    first day

    and settled

    they are tough small fighters, even more than lineolata
