Im not that great at explaining I can see. It would be easier to buy Joyce Wilkerson's book Clownfishes. But here we go...
The problem would be having two females in the tank. They would compete with each other, and one would be killed most likely. (juv -> male -> female) thats there lifecycle, they cant go backwards. Ummm... thus, you should only have 1 larger fish (female) for your tank. It is a small tank roughly, so... you can have only 1 female and as many lil ones as you want, they will compete to be male, no problem. I suggeest that you get two clowns. Easiest thing to do. If you want to breed them, good luck, but forget it. Hope I can get the points across... I do apologize if I am confusing you.
