I have B kweichowensis Matt, i've found it's a fish that likes to stay hidden until food goes in the tank then it's all over the place, it has S lineolata in with it that are slightly smaller than it and the Beaufortia rules the roost against them.
i've only seen them in shops as contaminants never a full shipment of them.

Thanks Mick, don't suppose you've got a pic or two (you knew it was coming /laugh.gif" style="vertical-align:middle" emoid="Laugh" border="0" alt="laugh.gif" />)? All the Gastromyzon I've seen on sale in Spain are labelled Beaufortia, wonder how that came about.

I have had a couple of B kweichowensis, like Micks mine would be happy to come out at feeding time and boss the lineolata and gastromyzons about but they met their match when I added the Sewellia sp spotted, the spotties took a particular disliking to the Beaufortia's and I soon found both dead and not long after my gastromyzons started following.

A shop I call into regularly gets "Hong Kong plecs" in on more or less every other shipment and they are always B kweichowensis, it is only on the last couple of shipments they have received some Sewellia as contaminants.

This is the only Beaufortia pic I have:

That pic of yours Matt also looks very similar to the fishbase photo of Beaufortia leveretti /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> and really neither of the fishbase pics look like my pic /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" /> /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

Charles thanks for the great images! What are the defining characteristics for B. kweichowensis?

Would love some but no way to put any tanks here at the moment. Why do you mention Zhou? You think he might have solid pics of B. leveretti?

I waiting for my first leveretti myself. there is one fact against the presence in the trade: the importers knwow only one species, not larger than 7 cm. and it's always the same species. in germany and switzerland it's the most common in the LFS's . so I've seen hundreds. sometimes I get even phones after incoming of shippments with ill looking specimen. that's the only moment when a confusion is comprehensible: they all look pale and the spots are not distinct.
the one pic shown which could show a different species: more flattened, (up to 12 cm) large and with finer spots. but: real news would be an identified specimen of leveretti. chinese scinetific listings of species in different regions even remark sometimes "doubtful"
kweichowensis has - in good mood - clear and well defined, large spots which can form a "net", others show single dark spots. there are specimen with a brown, green or red-brown solour, may be due to regional differences. but as the collectors keep the places secret - there is no way to know more. yous see: facts are rare.
AMAZONAS-magazine of mai/june is about "Flossensauger"=bodysuckers, from beaufortia to sinogastromyzon and there should be some pictures (Zhou and others).
cheers Charles

to cite a LFS owner: "I order b. leveretti and get anything" and a importer: "I can't change names like that, my guys wouldn't find the fish in the tanks." at least that's a funny excuse.
it's a curiosity of the trade that works with g punctulatus as well (for different species). If I talk to importers "I bite on granit" and you know I'm working on stone, granit as well. don't know how to change that.

So we should include this spotted fish as B. kweichowensis without being sure Charles? Or are we sure? /wacko.gif" style="vertical-align:middle" emoid=":wacko:" border="0" alt="wacko.gif" />

sure? as long I can't read chinese /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />
a cf is not what you want to hear, is it?
the pic by Zhou Hang shows a pale specimen as often seen when not at ease. spots look like washed out, the net-structure is not clear. but the typical dark borders of the paired fins are visible. at least it's the same species. if we follow the master's id ...
it's a mess I know. hope spring is coming soon.

Charles my missus can speak some Chinese. If you have any papers I can try and get them translated. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

The thing that bugs me about B. kweichowensis in the trade is that the species is supposed to be restricted to the Xijiang River in Guangdong Province, China. Does anyone know if exports of wild fishes from that area have been happening consistently for a number of years?

B. leveretti apparently isn't restricted to Hainan Island and ranges into Vietnam, plus there are several other poorly-known species from that country. Could one of these be the fish in the trade?

Looking at Fauna Sinica: Pisces: Cypriniformes III, B. kweichowensis kweichowensis and B. kweichowensis gracilicauda both seem to have a lot of dark pigment on the body. B. leveretti appears to be the spotted species we see in the hobby.

The mouth, lip and barbel structure is different on them all.

Here's a reply (reproduced with permission) I received from the gentleman who wrote this. He lives in China and his site makes interesting reading in general.

QUOTE
"Beaufortia are not yet farm bred. This species is wild caught and shipped over Guangdong Province, China. This is the Chinese capital for aquarium fish trade. Some fishes might be transhipped via Singapore. This makes sense, since almost all Singaporian trader are Chinese emigrates, especially from the southern provinces and speak Cantonese, not Mandarin. Thus communication is convenient. Initially B. kweichowensis was labbeled as 'butterfly pleco', then 'butterfly loach'. Chinese farm breeder mainly breed gold fish and live bearers, but also offer autochthonous fishes to offer more variety to customers. They recently discovered shrimps as an asset, now this branch is booming. They are breeders solely engaged in shrimp breeding, nowadays.

The fish on your pic should be B. kweichowensis. it has been described from Upper reaches of Xijiang River, Guizhou Province, China, known as the Pearl River, but also occurs in Guangdong Province. In this area there is good infrastucture, so fish tranportation to the Guangdong based exporters shouldn't be an issue.

Differentiation: B. kweichowensis has distinct black spots (vs. faint spots in B. leveretti), distinctly marginally patterned paired fins (black-white)(vs. no margins), anus location at the posterior border of ventrals (vs. anus below ventrals). B. leveretti has a prominent middle incision in the lower jaw.

Another very similar species is B. daon from Na Xam and Red River basins. The habitus is very much like B. leveretti, but no incision in lower jaw and anus midway from posterior margin of ventrals to anal fin.

I don't think there are exports of B. leveretti and B. daon from Vietnam. Both species occur in northern Vietnam. Infrastructure is far from convenient there, and all other interesting endemic balitorid species are occuring in central Vietnam, such as famous Sewellia spp. Anoter reason is that the aquarium industry in Vietnam is not that developed at present.

The first western author, who reported B. leveretti outside of Hainan was Kottelat, 2001 (Northern Vietnam fishes). Various Chinese authors report this species from outside Hainan, in lieterature or in the web. The problem is certainly Chinese language which makes the bulk of literature inaccessible for most of us.

Another problem is that there is currently no ichthyologist working on this group of fishes."
