Baby Clown Sexing

[Appaloosa1224]

At what age do/can clowns "decide" their sex? I have two bay clowns, one is about 1/2 inch and one about 3/4 inch. I have had them about a week and a half. The larger one is clearly "the boss," the smaller one is almost afraid, and usually keeps its distance. They do sleep together though. Is it safe to say the larger one will be the female? Also, they are not hosting anything, but I have places a frogspawn in the tank. They seem to like the GSP, but don't truly host it. Should I expect them to eventually chose a coral to host?

Although they have probably not yet completely determined their sex, I'd bet the larger more dominant one will become the female in time.

It really is a toss up on whether they will host in unnatural hosts. My true perc hosts a neon green hammer...
