My new Sewellia breviventralis/diardi/elongata

[Emma Turner]

I gave in to temptation and bought 10 of those new Sewellia home with me yesterday. I have put them in the 4ft river tank where my S. lineolata and S. sp. 'spotted' live. At first, the Spotties seemed quite angry, but they seem to have settled down today and I have even observed some interesting behaviour between a male and female of the new species already.

I took a few short (30 sec) vids last night when I fed them, quality is not brilliant, but you'll get the idea. Please turn the sound off so you don't have to hear the noise the camera makes as it refocusses, and also the annoying TV programme in the background (not my choice):

This species is capable of dramatic colour change depending on mood and what it is resting on.

Great videos, Emma!!!
Those are very attractive fish. They look like a cross between P. cheni and S. lineolata.
I wouldn't be surprised if you are posting pics of their fry before too long.

they are amazing! i love the yellow fin colour, and the patterns. i need a hillstream tank.

we shall have to get practising for how to best represent these in our photo gallery

Gorgeous!!!

And the videos are not bad either....

[Emma Turner]

Thanks guys. Here are a couple of quick pics I took this evening:





I definitely have both males and females of this species, most of the males are huge with prominent fences on the pectoral fins. If I was fortunate enough to have them breed, I would have to hope that some eggs get drawn into the filter as at the moment they don't stand a very good chance with my pair of Mesonoemacheilus guentheri in the same tank (this is temporary, they will be moved at some point).

Hels, maybe the less said about our own personal photo gallery the better?!

Those pics are interesting.
Most of the pics I have seen of this species show it to have a light brown color with yellow dorsal. In these pics, the fish look yellow all over.

[Emma Turner]

Mine are definitely darker in colour than the pics I have seen from other people. However, I have seen them go through dramatic colour changes when bickering or when resting on different coloured substrates.

You named it in one Jim. (colour changes and all)

Thank you for a splendid video.

Their dorsal fin seems to be bigger in comparison with the close species for me when I observe your video.

Unfortunately I cannot confirm the import to Japan of the fish for the moment.

They are stunning!!!!!!

Brilliant photos as usual Emma!!

hi emma
it's great to see them in action!
finally I got the "diardi/"breviventralis" (jörg freyhof hasn't fixed the species yet) last friday. what a joy.
and what a surprise: two different species together. the second with different pattern , different shape of head and so on. that means, one more "new" sewellia!
as soon as I can make this machine work for uploading my pics we can see the "new" one.
the situation is this: in DATZ 05/2005 j.freyhof presented 8 species with pictures (not diardi). of course it is not possible to jugde after a picture taken from ahead. but s."breviventralis" looks like s. elongata. the new one is not present in the article.
the two in vietnam later descripted "new" sewellia are doubtful nd not verified.
I hope the "new" are as "easy" as lineolata/spotted. specially the fast growing spotted are a hit-and they don't stop with the making of.
wonderful!
with greetings from swtzerland

I got these photo's in Pier Aquatics the other day:






There were at least a dozen males in the tank with raised fences and they wouldn't sit still for me to get a decent pic of them, looking closely at these and going by Kottelats description I would say these are Sewellia elongata

[Emma Turner]

My supplier came back to me with more info and they are now being listed as Sewellia breviventralis on his stock list. I am still trying to find out more on collection location.

hi emma
collection location is vietnam, province Hue, Mo Cascade. mo cascade is not possible to find. there is a river near A Loi going to the mekong. elongata and speciosa have been found there. the "new" species, described in vietnam come from there and could be the already described speciosa and diardi.
the sewellia on mimbon.de is definetely not breviventralis could be diardi(all communication j.freyhof).
that means: breviventralis is out, in comes elongata or diardi. or else!
so we start again. in german we call this "schnitzeljagd" = hunting little pieces of paper.

Hi all.

I found the website where their habitats and specimens of several Sewellias were mentioned in.
Sewellia albisuera, S.breviventralis, S.elongata, S.lineolata, S.marmorata, S.pterolineata, S.speciosa.
Unfortunately the content is unclear because it is not English other than a scientific name.
However, the position of the habitat is shown on a map.

The article of this LOL site seems to be introduced, too.
