The following pics show a small spwning sequence of a S. speciosa male with a S. lineolata female!!

The male paired alternately with the speciosa and lineolata females.

I know that the pics are not very clear, but I think you know what i mean.

At the second pic you can clearly see the interlock. The spawning looks exactly like the lineolatas.

Some of my fry really look strange, I suspect nothing good......

That's very interesting. I have wondered when this would happen to someone. I have expected lineolata and Sp01 hybrids.

Can you get pics of the fry for us?

Congratulations!
Photos, photos, please!

I think S.lineolata and Sew01 are rather different... but S.lineolata and S.speciosa did feel closely related. Now, Sew01 and S.albusiera...

I also think so, the same behavior body shape and size may be a clue.

Sew01 and lineolata are to different, Sew01 and albisuera are very identical.

I have already posted pictures of a strange one here:

Only that one have the strange head shape but some others also have the same markings.

The fish with the strange markings grow even slower than the others.

The one from the post 9 months ago have now a TL of only 3cm!

Here's a pic with a adult female and a junger one how have different markings. Much more spotted and extreme slow growth,

I think that coud be the hybrids?

So much for 'hybrid vigour' huh? Laugh

Very interesting stuff though. Are any Sewellia produced on a commercial basis yet?

Cake or death?

I know nothing about it. All wild caugth, one problem is the slow growing and the small final length of aquarium bred Sewellia.

They need Aufwuchs around the clock!

On the productivity, it does not fail.

It may prove to be that interspecies hybrids of Sewellia are unable to reproduction.

It is even more interesting whether the Sewellia hybrids are actually able to reproduce. As an evidence of closely related species.
