We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
Hey
So last time we bought 2 adult males. Now we need some females to keep them happy. We found a seller who is selling these 6 zebz. I got these pictures from him, hopefully you could tell something from these. Are there any females in the group and how long it would take them to be mature for breeding?
From the look of it, these 6 zebras are relatively young fishes, which is about 2 inches +. Most of us will rated them as "unsexable" at this stage.
Now back to your objective,
1) If you hope that they can breed for you in less than 6 months, this group is not possible as they are not fully matured yet or well condition to breed.
2) If you can wait much longer, such as more than a year to condition them and to allow them to grow till adulthood, then you may be rewarded with a few females eventually
In my opinion, getting unsexed fish would be cheaper as compare to buying confirmed female or breeding group. If time is not a factor, you can even start consider the juv fish of 1.5", which is cheaper and more rewarding, when they eventually breed for you.
Well our problem is that we have 2 adult males and 1 nearly adult male. But then we have 4 juveniles, that are 1+ inch. There might be females in those 4, but it would take probably 2 years before that is clear. So thats why I'm trying to find females. In Finland there are no adult zebs on sale, so I'm kinda stuck with these nearly mature ones.
If you have top shot of each individuals with size, I might have a better chance to sex them.
Out this group, I do see at least one mature female that is ready to breed soon. My experience is that some female can be ready to breed as early as about 2.5 years old. How ever, it might take a lot longer up to 4 years for the males to get ready.
