These were seen today labelled as S. elongata (sorry for the poor photos):

They look like mine seen here.

Hi, yes they appear to be the same

yes, in any case it looks exactly like the species picture of s. elongata in DATZ 2003 by J Freyhof. no picture in the revision in 2000.
the species with the yellow bordered paired fins shown by Kamphol in Amazonas-Magazin mai/june 2010 is different in patterns too. and what is irritating: the pictures of the holotype in ROBERTS revision (1998) show the species of Kamphol, not "our" elongata.

1cm fry of the above species:

Sorry for the quality of the photo, the fry is mostly hiding and its presence was noticed only today /biggrin.gif" style="vertical-align:middle" emoid=":D" border="0" alt="biggrin.gif" />

Congrats Mike /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />

Sewellia do seem to be the most accepting of loaches when it comes to spawning in aquaria, that said it is still an achievement spawning and seeing young from any of them

Nice work Mike. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> So you have mature adults then?

Thanks guys,

I have a group of eight young adults, barely 1.25". Given their size and my inability to sex them, this fry is a surprise. Another surprise is that I had the adults only for one month, the fry, however is already 1cm with almost adult markings.

Nice looking fry Mike, looks exactly like a small S. lineolata.
I have a question, how big are the adults?
Until now my specimens make no signs of a courtship.

Is there any possibility that this could be from another loach Mike, I know you have bred other species so could an egg have been transferred or left in the tank ?

I only ask because as you say the adults are still small and the fry so big for 1 month which would mean that this would be the fastest growing fry.

Just being devil's advocate really as I know you have had a fair bit of sucess with hillies and many others /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Your suspicions are warranted, I'm having the same thoughts right now.

The only contamination chance is that the sponge filter came from a tank that has Lineolata in it. I never had any fry from those lineolata's due to their tankmates and filteration.... but I guess an egg could have been in the filter, even although I cleaned it extensively... this would mean a lineolata growing from an egg to 1cm within the same month.

Let me try to take a good photo of the baby when I see it again. I believe that the pattern on the front half of the body is different (lineolata==more mottled).

Good stuff Mike! Hope it's an elongata. Since we both got them from the same place at the same time, maybe I'll have some fry when I get home??

Jim, I hope you do, but I'm getting more suspicious that this may be a S.lineolata (filter transplant) after all. The pattern on the front part of the body matches too, and our fish is juvenile (albeit I did see courting behavior already).

I'm unable to take good photos of this fry for now... it will not come out when the tank lights are on, and it will not approach the front of the tank either... /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" />

Well, we'll know within a couple of weeks...if no additional fry emerges, it is unlikely to be S.elongata.

I have to withdraw the claim, sorry !

The fry developed into a S.lineolata.... contamination from the moved filter. So much for the excitement....

Maybe I'll have something new to show yet, this little chap was found in another tank yesterday:
[Image Can Not Be Found]

The ID is not certain yet, the tank has two Pseudogastromyzon species and one Vanmanenia sp, could be any of them.

Cool. /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Head shape possibly more reminiscent of Pseudogastromyzon?

My feeling too, but hillie fry tends to change drastically, need to wait and see. Another reason to think that it is a pseudogastromyzon is that I saw both PG species spawning repeatedly, but have not seen Vannies doing it yet.

For clarity, if it is a PG, it is either P.fasciatus or a very similar (shape/size) spotted PG I don't have an ID on:

P.peristicus is a guess only.... if someone here knows this would be nice.

Here is the baby with P.fasciatus female:

Cute! /wub.gif" style="vertical-align:middle" emoid=":wub:" border="0" alt="wub.gif" />

Edit: could be P. peristictus based on Zhou's pics but I've even stopped writing profiles on this genus for now since they're so hard to identify.

Hi Mike
headform and the spot make it look close to young p. cheni. could be p. fasciatus fry. Hope to see more /thumbs_up.gif" style="vertical-align:middle" emoid=":thumbsup:" border="0" alt="thumbs_up.gif" />
it's certainly not p peristictus, Matt which has fine and dense spotting. I even doubt that it's pseudogastromyzon. may be beaufortia?
