clownfish are all born males and the dominant male of a group will turn female when the female of that group dies.
the clown fish are all born male but they have to chaange gender into a female so they can mate with the domonaite male
Quite a lot of fish are Hermaphrodites, they can switch their sex as they mature and become breeding stock.

if female beta fish are put together they would start to fight like the males.
