Sewellia numbering yet again.

Two things:

Looking at S. albisuera profile it strikes me that photo #1 and photo #5 (which likely shows the same fish) appear to be Sew01, variation with reflective areas. Suspicions about this photo were raised before on the forum, but at the time I was not yet aware of the existence of the reflective variation.

Perhaps the reflective variation should be added to the profiles (suggested name: Sew01R, to indicate it may be a variant of the same species), and these photos moved there?

Secondly....

Wetspot (the largest importer in the US) asked me to comment on their Sewellia shipment.... specifically they wanted to tell Sew02 from Sew03.... well, I could alert them to the likely presence of Sew04 in the shipment (sure they were there), but as for their question naturally I could offer no solution... I personally believe that unless we have a clear way to tell 2 from 3, there should not be two entries.
Wetspot decided to label them Sew03 all.... they could have equally called them all Sew02 ... we don't know the difference!

BTW, they did manage to screw this up further... after saying they understood Sew0203 vs Sew04 and looking at my and SF photos their article on the new fish had photos of Sew0203 both for the Sew03 listing and the Sew04 listing.wssew03.jpgImage Enlarger

the "Sew04" photo is strange...

Needless to say they screwed up my order too :( :( :( but none of the Sew04 I got looks quite like this.

Interesting. This one was labeled sewellia "SEW04" and also bought from Wetspot:

 Not even sure on the ID. The "SEW03" was the funny looking one and was not any of the photos they had.

It is an 0203.
They have difficulties telling 03 from 04.

Did the other one happen to look like this one too?

When I asked them about the species, I was told it was a mix of three different ones. I think for now, I will just call them sewellia sp.

The last photo is a Sew04. As a guess, female.

I do not think there are three species there albeit their 2nd photo (see first post on this thread) is intriguing. Possibly just older Sew02/03, possibly something new.

Mike, I agree re. Sewellia 02/03; think they are the same and will amend asap. Maybe SEW01 is just S. albisuera and there are several colour forms? I will try to get an official opinion on this.

P.S. I didn't realise we were influencing trade names! Unsure if good or bad at present.

It is probably a cluster that includes S. albisuera, Sew01 and Sew01R . We can tell them apart, but if they are all the same species or quite different one would not know until someone did the DNA testing, and even then there may be different opinions. That Sew01 is quite breedable and I have not heard about Sew01R being bred may be an accident or point to some real differences.

P-S- I didn't realise we were influencing trade names! Unsure if good or bad at present.

I may be a bit guilty here, I sent them to SF profile several times, and probably plaamoo did too.

Good thing IMHO, when vendors provide links to SF it brings more people this way.

BUT: this means be more careful with things you cannot defend they got really confused over Sew02/03. And when you delete Sew03 profile (as you should imho), you will confuse them even more!


Oh, as a joke: feel like really influencing names? How about calling Erromyzon Red Spots (Er01 I think) Erromyzon rubromaculatus? The namei is fitting and correct Latin-wise. :P

Agree, and yes, I am also guilty. Many times :) Some times they listen and sometimes not. I wish they'd fix that "Tweedie's hillstream loach homaloptera" listing! Homa

This one: http://www.aquabid.com/cgi-bin.....1414600809

I told them too. I even had Anthony check that they actually do not have any fish like on the photo. But fixing the listing... forget it, so difficult :(

That's the one. Fortunately they sold out of "Borneo sucker loach gastromyzon myersi" :)

Don't you worry about that, they will get it again and use the same name and photo.....

Not the first time.

I think we can get away with using numbers but feel it would be irresponsible to start giving things scientific names. We need to be careful. SEW03 will shortly bite the dust when I arrive to Sewellia - currently working my way through this and updating the relevant profiles.

Hi all

Can log in again, thanks Matt.

The problem with the importers is well known. The actual shippments are mixed anyway: the "new" species, Sewellia SEW04, Sewellia SEW02 and 03, Sewellia breviventralis (the real one) and subadult Sewellia elongata (?) inclusive.

In a mixed tank I couldn't tell them apart by the pattern. Seems to become a problem when they are adult. And more: just saw a specimen yesterday which looked like the newly sold species - Sewellia breviventralis at Glaser's, shown above.

I remember a remark by J. Freyhof: SEW01 - sp. "spotted" is not albisurea.

So what conclusions? I have restarted, seperating fry out of the mixed tank. Adult should be follow soon, trying so separate 02/03. And of course the new ones coming in tomorrow.

Cheers Charles

Good stuff Charles, glad it is working now.Smile What is your opinion of SEW02/03?

Mike, apologies - hadn't noticed the 'joke' part!

Matt, one thing:

if you end up deleting Sew03 (which imho must be done if there is no working way to tell it apart from Sew02), do not totally delete the entry, rather replace it with "See Sew02". Rationale: there are references to Sew03 now.

Sorry Matt yesterdays post didnt pass.

To make it short: there were tree different species in the shipment then. Different headshapes, different pattern in fry up to adult stadium.

I got 10 of the new shipment today: different species too. As Ingos pics already showed: a mix. We are going to breed and document them.

Cheers Charles

I have not seen anything but Sew23 and Sew04 in the previous shipments.... but with the new ones there may be more than usual variety in sew23 ... need to look at them yet carefully ... plus I'm not sure about this fish:

I put it with Sew04 initially but it seems different now... possibly badly colored sew23

Some news from my side; got some more fish that looks like S. albisuera, now I have males and females. 

Interesting new headshapes.... 

Pictures coming soon.

All of them look different compared to SEW01.
