Finally got some pics of the 5 bettas i still have left from http://www.fnzas.org.nz/fishroom/fighter-eggs-just-hatchedwhat-do-i-do-now-vt26504.html
Im not too sure on the sexing mut this is what i think.
This guy is a male i think.
And his little nest
I think this one is a male too,its the biggest of all and sometimes flares at the platys like his dad does.
And these two i think are female,as they never flare,are smaller and no bubbles yet.
Thanks,
Please let me know what you think about the sexing of them.
