Marlin (Nemo's "father" in the movie) would have also become the dominant female after Coral(Nemo's Mother) dies. so in the movie for most of the time, Nemo's "Dad" is actually a female.
Company will come over and they'll ask, what's that. My wife will answer that's Nemo or that's Annabella. And she'll say, Mike knows the real names. I'll say that's a Premnas biaculeatus and that's a Euphillia Divisa. They usually ignore me and like her answers better.

And so riding on that fact in part 2, Marlin becomes Marla and Nemo becomes a bonded pair. That will freak out a lot of non reefers and confuse lots of kids LOL.
