WoOt!

The First recorded aquarium breeding of Sewellia. The dream of Dreams Hillstream Loach!

Do ya reckon

It'd be amazing if they are.

Going by the fins, that is what I have been inclined to think.....hmmm........

Just look at Martin's face! He's not a happy bunny! lol

Heheh! But we must remember that whatever loaches have bred, they have bred because of a combination of Martin's excellent manifold design, ideal water params, and good healthy group of (beautiful) loaches.

Oh, and sheer luck that I found them in the filter!

I found these photographs which show the underneath mouth parts of adult Sewellia. They were some of the ones I had taken of those two males fighting in the tank at work. Definitely 'something going on' underneath there:

So it's looking more likely, however, I'll wait a little bit longer before I'm fully convinced!

My friend Mr. Plateen of other boards told me that mini loaches he preserved from Laos were id as Sewellia species and still have distinct head compared to adults. If that is true I think Emma's fry are indeed Sewellia.

BTW has anyone spawned Gastromyzon?

Some time back, someone posted some pics of baby Sewellia lineolata with an adult. Both had been captured. If I remember correctly, the young was very yellow. Of course, captive bred fish may lack that color.
The mystery deepens...

Here's a link to that thread, but I can't get a pic

To many question marks there Jim. Recorded pictures of the actual fry development is more convincing. The picture is no longer available from the link. Such a shame. It could of been the 1st definite sighting of spawnings. With not the full actual sightings.

Not really. I won't be upset if they are Sewellia. Couldn't happen to a nicer person

However, not wishing to pee on any fire, but I edited Emma's DAaaaaark
Anamia picture to get a bit more light and clarity into it.

It looks somewhat close in general mouth shape, gill area, position of anus compared with pelvic fin origin, etc, than does an adult Sewellia. Also, the main muscle groups around the fin bases which are very visible in many Balitorids again look closer in general form. Because of the darkness, you can't do an accurate ray count on the adult pic to compare with the baby pic.

I'm totally willing to be shot down and proved wrong, but I'm still leaning toward them not being Sewellia. I shall be highly suprised and pleased for Emma if they are.

Like I said before, this is a "no-lose for loach lovers" thang anyway. You go girl!

I can not agree more with the 'no lose' theory, Martin.

I can see the Sewellia's mouth shape in the pictures. Cant you?

Jim Powers · Post by **Jim Powers** » Fri Jun 30, 2006 4:51 pm

I'm betting Martin would be VERY happy if they were Sewellia fry.
Knowing his experience with breeding two other hillstream species combined with the fact that he has Sewellias would probably increase the chances of him finding Sewellia fry in his tank.
Of course all that would only add to my frustration at not finding this species, but I would just have to learn to live with it.

Well, I have managed to get a better shot of the underside of the smaller Annamia specimen by having a go with the expensive flash I got a few months ago (but haven't got around to reading up and using properly yet

)....

You can see the space between the pecs and ventral fins, plus the clearly forked tail.....

and baby for comparison once again:

Nope.....

I would call a Sewellia mouth more of a 'C', while the Annamia and the baby fish have more of a "crescent moon" shape..... as far as I can see (at present) [Your mileage may vary] {Objects in the mirror may be closer than they appear} (Caveat Emptor) {You can't get quicker than a Quick-Fit fitter].....etc

New engine? New factors!

Lets see!

Martin Thoene · Post by **Martin Thoene** » Fri Jun 30, 2006 5:26 pm

OK Emm......now you're screwing with my mind..... Pelvic ray count is WAY off compared with the baby, and close to my Homaloptera smithi but the baby is the close to a Sewellia count of 19-21. Trouble is you can't easily see all the rays.

Sewellia are notable for having very high ray counts compared to other fish, so.......

Fingers crossed. Keep snapping, this is going to be fascinating......
