few months ago I've bred a pair of betta albimarginata, leaving me a total of 11 offspring, now, at the average size of 3/4 inch, they rarely show their body color, but the fin color is showing consistently and I'm trying to know which of them are males and females...

from my personal view, a male betta albimarginata has clear white banding on both anal and caudal fin while female has either no white banding or slightly visible white banding, but I'm not sure if it's right or wrong

can I know the proper way of sexing betta albimarginata juveniles without using the coloration method?

thanks

at that size the white band should be visible on the male and the females will be just a brown colour with mottled colours... if you have a dark tank its easier to see the white band. Fairly straight forward

well done breeding them /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Worst problem I ever had with these fish was that I bought channoides and albimarginata at the same time and they arrived in a box together. The box was partitioned with newspaper but some of the small bags were mixed up and I had to try and sort out between the two species!

How did you do that Colin? This is a confusing one for me...

the easy to sort out the male of both species, but female, probably a disaster to me, you are truly good at these 2 /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

no, not so easy... okay if in full breeding dress with males but i ended up with three tanks of fish, the third was for "undecided" and I have to say that some of those females never got to see a male of either species because it would be irresponsible to mix the species.

I tend to think of albis as looking longer and thinner in the bodies compared to channoides but why take a chance? I am sure they would cross easily?

i have both species today but happy to say that just now they are kept about 400m apart /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Is there much difference in body colour between breeding males of the two Colin? The photos on the IBC site show B. albimarginata as an oranger-coloured fish with thicker dark markings on the fins and having never seen a live one am curious if it looks like that,

for male, it is pretty easy, look at the caudal fin, channoides has rounded tail while albimarginata has a delta looking tail, might be an indicator for females too, but I don't think it is going to be easy

yes, I have seen channoides display a much more red colouration and generally darker than the albimarginata. It's fair to say that that the male albi is more orange -

No decent channoides pics as they are in the shed but here is albi...
