    Care to share pointers on how to differentiate the sex of Betta rutilans?

    Is it possible to house them together with Sphaerichthys vaillanti?

    From what I read, they look similar. Does that mean we have to buy a few and let them sort it out themselves?

    From Labyrinth Fish - The Bubble-Nest-Builders by Horst Linke, this how to differentiate between the sexes for Betta macrostoma. The females are likely to retain their longitudinal stripes, while the male are more vividly coloured without any longitudinal stripes.

    My rutilans have already settle down and displaying their reddness from head to tail. I've a couple of them who are as red as the others but with quite prominent longitudinal stripes. Not sure if this is an indication that they are females.

    I've bought 9 pieces, so hopefully have higher chances of getting both sexes.

    The lower piece has a longitudinal stripe. So could be a female.

    Hmm... I am not sure if that is some kind of sexual dimorphism. Longitudinal stripes may be a sign of stress. My male B. coccina do show such stripes from time to time. *shrug*

    I have read that B. rutilans seem to be intolerant of their own type, rather aggressive too. How are the 9 of them co-existing together?

    Haven't seen any confrontation yet. But all of them don't seem to swim close to each other. Everytime when one crosses another's path, it will avoid and swim away in other directions.

    Think as with most territorial species, as more pairs are placed together, the aggressive is very much spread out among them. So should have no issue housing them in a large group together to get them paired up together.

    I have a pair myself and they are a true pair because of this ...



    The female seems to have slightly shorter dorsal fin (one of the easier way in other species as well). At times the body colour is less intense and the belly region is pale (vs uniformly red male).


    (the male fish)

    Now they are into 4th spawn but unfortunately no fry yet.

    Wow!! That's such a beautiful fish! The photo does give it justice.

    Cheers,
    I have dwarf cichlids in my tanks! Do you?

    Hi Zaz, very professionally taken photo. Thanks to all for the inputs. I also have those bubble foaming but I dont expect much cause they are housed together with a pair of macrostoma.

    As for other small fishes, they are best kept in species tank preferably in pairs. If you can ID them.

    Finally got a decent shot of the female. No gross difference compared with the male. Even the fin length is similar.

    I was looking at these photos

    http://www.ibc-smp.org/images/rutilans/rutilans15.jpg

    and it suggest to me like the male is mouthbrooding. There were records mentioning that they mouthbrooders.
    Wonder if they did evolve from mouthbrooding to becoming a bubble nester.

    Just sold off my B. rutilans to raise B. rubra fries. Setup nothing interesting. Just some branches and ADA soil. I've not breed them before and my setup may not be ideal.
