Hi again. I am totally flooding this forum with questions. I apologize if you're annoyed; I have nowhere else to go with this stuff.
I got a bunch of giant MHPK babies on Friday. They are 10 weeks old. I cannot sex them for anything. I have looked for ovipositors (they all look like they have them), tried to compare finnage (all short), look for little "beards,"(ha ha that's silly) check for aggression (although this can mean nothing), and just about everything except ask them about it, which my husband has suggested. Which may be just as successful as my observations.
The ONLY difference I can see between bettas is in the ventral fins. Some have very long, pointy ones. Others have very short ones. Some don't even look like they have any. Can I use that as criteria for sexing? The two red cambodians which i KNOW are female per the breeder have little ventrals.
It isn't a safety issue, as all aggressive ones will be jarred. However, some of these babies are going to be rehomed by people expecting a certain gender. If that is wrong, there's gonna be some angry people asking me to ship them new bettas for free. Help, if you please!! Thank you a lot.
