    Superb pics Charles and very, very nice fish! I will try to revise Sewellia profiles soon.

    Have wondered about the purpose of those metallic spots in Sewellia before. Do the fish intensify in colour when breeding? Do they tend to spawn at a particular time of day?

    Give me more time. Matt. they just arrived Laugh

    It seems, they don’t change when spawning

    My pics of S. speciosa spawning show the pair from the ventral side.

    One at the beginning of the act

    Some pics of my small ones, of course no comparison with Charles, but the markings are very similar to adult already.1.jpg

    Sewellia marmorata reminds me Beaufortia sp. in a body shape (especially their head). If I’m not mistaken, and they are really close evolutionarily with beaufortias, it is likely to be expected difficulties in breeding of. S.marmorata in the tank like in the case with beaufortias.

    Has someone already got S.marmorata fry in the tank?

    Sewellia SEW 02 were more efficient lately in a identic tank-set. I don’t think, S. marmorata is different in spawning. Saw some attempts, but no offspring as for SEW 02.

    Hi Charles! It is well that mormorates are trying to spawn. We will hope for a successful event and wait for it.Smile

    Mine are only chaising each other and that’s all.

    Hi

    Just noted first fry of S. marmorate, about 11 mm long.

     Pattern is different to other Sewellia fry at this age (about 4 weeks)

    Hi Charles!

    You are the first who bred Sewellia marmorata in the captivity. And now the photos of eggs from the spawning on November 4, 2016, prolarva on November 6 and today’s photo of larva of my Sewellia marmorata.Sewellia-marmorata-eggs1.jpg

    How are your Sewellia marmorata fry doing now?

    Hi Olly

    That’s great to see. How do you breed them? Coconut-style? Confused

    Seems, they do spawn greater quantities?

    Mine seem to do well, but actually I’m moving household, atelier, storage places and soon breeding room. So there’s not much time to watch.

    Cheers Charles

    Hi Charles!

    Thank you!

    Good luck with the move!

     I think that there were more than 90 eggs. Here is the most part of them at this pic (about 70). Most of them are not fertilized or were not survived. Size is about 1 mm. Only two females are in my group of S.marmorata. It is likely that all of these eggs are from the spawning of the one female. She was greatly swollen and excited with unusual behaviour in the morning of that day. Another female was thin, and I think (but  I cannot be sure) she was not involved into spawning. It is likely the egg productivity of a one sewellia is pretty high.

     Fry have great appetite, but grow very-very slowly.

    I did nothing special. A year ago S.marmorata were young, now one female became gravid. That is great that parents were synchronized. I did not see their spawning (only gravid excited female in the morning and later eggs and dominant male with high frequency of breath and high heart rate), and I was not sure that eggs were fertilized. But fry appeared 🙂

    Good stuff Olly! How do you spot the eggs in the substrate?

    Charles, I hope the move goes well. Moving is a special nightmare for us fishkeepers!

    Thank you Jim!

    I think I returned at home at the moment of the end of S.Marmorata spawning. The eggs were still on the substrate (the first picture above), and they were not eaten yet. I guess that the light in the tank interrupted the spawning. The Sewellia’s eggs are very adhesive and they were glued to the substrate.
