RE: D.maculatus
Ken
If I'm not mistaken at one time both of these fish were or possibly are in
the same genus. where and why they may have changed well you know how we
love to reclassify things ;).

Mmm, isn't it Crenicara punctulata that is known for the sex change? Maybe
D.maculatus does also. Anyone any further info on this?
Ken.

I've heard that D. Maculatus is one of the few freshwater species that can
actually change sex dependent on presence of males. Much like many saltwater
species do, the change is male to female. So you may try pulling the males
as they develop to see if you get a higher percentage. No proof it is just
what I've heard from reputable sources.

I don't recall the age, but I do remember that it took a while. Both Julio
and I
have been having a very hight female ratio. I once thought I had 9 females
to
every male. However, it seems that some males are subdominant. When I
remove
the obvious male, another fish might take his place as the obvious male in
the
tank.
But if the fry are only 3 months old, I wouldn't panic...yet. I can see it
taking 5 months or so before any males emerge. I'm pretty sure that they
were
well over an inch before showing. (Next time, I'll have to document growth
with
photos.)
