Well, there are two ways. You can wait and see until Ur male gets the fatty hump on his head, or you can vent them, when you vent, u turn the fish over and look at its holes. If its s male the holes will be the same size, but if its a female then the last hole will be bigger then the first.
Male= o o
Female= o O
I wasent able to vent mine until they where about 8in. But when they get to about 8in, I see a very different mood Change some times. The first time I tried to vent mine, my biggest ripped through the net, so what I did is held the food over the tank and made them look up, when they did I was able to the holes, so good luck and hope everything works out for u in the Long run. Oh and welcome!!!!
