    Does anyone have any details as to the correct scientific name for the Rosy Loach, some places are using the probably ficticious name Tuberoschistura arakanensis and others just list them as Yunanilus sp ?

    tuberoschistura is a classification on loaches, Mark. arakanensis is not valid.
    for me it seems closer to yunnanilus by body-shape than to t. baenzigeri – the only tuberoschistura-species – out of two – with a picture on fishbase. no others elsewhere.

    Personally I think it is more likely Yunnanilus, I just wondered if a proper description had been done that I have missed

    For reference: To check if a name is valid [it won’t tell you if the species is what you think it is!], I use Catalog of Fishes:

    Cheers Mats, that is a good site, I have used it quite a bit of late

    CAS is much more reliable than Fishbase.

    Just wanted to post a quick note to say that I’ve just got my first rosy loach fry :)

    Exactly the same setup as for breeding the Sawbwa resplendens earlier (20 litre tank, full of plants and moss, a few shrimp and a mesh to protect the eggs. Put in a trio and left them to get on with it for a few days. Just spotted the first two wrigglers today, so removed the adults and will have to wait and see how many I get (probably only a few).

    That’s great news Tom! When you say ‘wrigglers’ do they still have a yolk sac attached or free swimming already?

    One free swimming, one still with yolk sack. Plus a few eggs scattered about but I havn’t been looking very hard. Adults were in for about 5 days I think so I don’t think they wasted much time.

    PS, are we largely agreed on Petruichthys sp. ‘rosy’ as the correct name for the time being?

    They’re not giving me many photo opportunities, but just got one on the glass.

    2 days old I think (maybe 3). Small (just over 4mm TL) but not quite as small as the Sawbwa fry at the same age and seem to be more developed, with a visible caudal fin.

    For the record; pH 7.45, 215ppm, 22.5 degrees.

    That decision was based on this short line from Conspectus cobitidium Kottelat 2012: ‘Yunnanilus brevis and some unnamed

    species from Myanmar are placed in Petruichthys.’

    Yunnanilus is considered as restricted to China in the paper so yeah think placement of the rosy loach in Petruichthys is ok?

    Great pic of the fry. Smile

    Sounds reasonable, I was just wondering if the Kottelat quote had been expanded on really. Fry seem to be doing well, very active and constantly on the hunt for microfauna. I’m not feeding them anything.

    Fry seem to be coming on OK.

    Voracious little eaters and really active – already hovering about in midwater like the adults do sometimes.
