There have been many claims of sex reversal, but very few are provable. To be a
true sex reversal a fish has to be the only female in a tank and produce fry. It
must later, after sex reversal, it must be the only fish (of that genus) in a
tank with a proven female (one which has laid eggs before) and then produce fry.
Otherwise there is always the question of who actually laid/fertilized the eggs.
"Females" that never laid eggs can very well be sneaker males. "Males" that never
fertilized eggs could be females showing masculine traits (an effect of fish
menopause?).
