Hi all,

What is the latest scientific conclusion on the sex change
in freshwater livebearers like Xiphophorus sp.?

Is it true sex change? Is it considered an apparent sex change
with late-developing males? Is it a change in hormone levels
in females causing them to develop male-like characteristics?

References would be great, if you have them.
