If anyone is curious (as I was):

Nemo's dad would have become female after mommy got eaten.

And mated with Nemo. Let's not forget that.

Salmon change sex too if I recall correctly.

I don't think salmon change sex to be honest. It seems from the stuff I could find that sex determination for salmon is mostly chromosomal but with divergence at certain temperature during development (or exogenous hormonal influence obviously).

The coolest paper I found while searching was this:

No, this is just saying that they have the chromosomes that usually produce male salmon but they have female salmon genitalia. I read that one. Unless I misread they haven't seen these salmon be male and then later female (like the clown fish do).
