I positive there are males, unless my females decided to not have the tell tale white stripe on there back. I've been thinking about getting some new males and females to put in the tank, but I'm a bit broke ATM. To many medical bills.
My tank is small e nought they shouldn't have any trouble finding the females to mate after they molt, and there are no predatory fish in the tank.
must....have.....more....moss n shrimp!!!!!!!!!!
