Hi, I got a 30gT tank with 2 fish in it. One of which is my clown, the other being a purple tang (who will end up in a 75g.
I have read that you can have two clowns together and they do well, as one will become male, the other female if purchased young enough.
I've had the one clown for about 4 months, and he's happy as a lark. My daughter would like to have two clowns. I do have the option of placing the tang and the clown in the 75 at any time, but was wondering can I get away with buying a very small clown and placing it in the 30g tank? At what age would it be to late for it to change sexes? I would assume that the clown that I have is already determined (and seems to be fairly small). Would I be safe in adding a small one, and it becoming the female (provided what I have is a male) or the opposite sex?
Hope my train wreck of an idea make sense! Thanks in advance.
