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!).
Tough one, they look like sub-adults that need fattening up, then take some more pics in 6 months +.
I can see some young males, too hard yet to tell any females yet.
First batch looks male heavy, second batch the ratio looks a little better. Get those guys in a tank with good food and constant water changes, and it will be much easier to sex them within a few months! That's alot of zebras! Did you get them locally or have them shipped in?
They are locally purchased. We did a group buy of 40 L46. I will fatten them up and will post pics again in a few months. I know it is kinda hard to tell when they are so skinny.
