Female changed sex!!???

I think the correct term for this phenomena is Sequential Hermaphroditism. Several google search results list fish as being one of a few different types of animals that this occurs in.

Hi all,

This is slightly different, the old female fish doesn't actually change sex, it just develops some male characteristics.

There is some debate whether Crenicara spp. can change sex, but I'm not sure what the conclusion was. I think marine Clownfish, Damselfish and Wrasses are reasonably closely related to Cichlids in evolutionary terms. From <"Functional hermaphroditism in teleosts">

This overview documents the incidence of hermaphroditism in teleosts and explores its phylogenetic distribution, possible origin and range of expression. The review confirms functional hermaphroditism in 27 teleost families in seven orders, predominantly among tropical, marine perciforms in which its diversity of expression is greatest.

That's assuming it isn't a true transition and that the spawn he's been documenting is from the other male, but they've been separated for a while now, haven't they?
