To test this, I would set up several groups of DGs, of at least 5 fish,
removing the dominant males from each group as they appear. Eventually you
will either end up with all females, or a lot of pairs
I am not sure of the size of the sample groups needed to validate this,
but a large enough sample should give those interested some idea. And
anything to do with the keeping of large numbers of Desert Gobies (AKA The
Fish They Breed In Heaven) can't be too bad. :)

Bruce, my question is the same as Harro's. Change functionally or just
colour? No goby in the desert gobies' subfamily is known to change sex. So
Far. "True" gobies can change from female to male.

and >not vice versa.
Do you mean this biologically or just regarding colour? Have
had a spawning female which later turned into a male with 100% guarantee?
