Mike,
Thanks for the advice.I appreciate it.
I have two M.altispinosas at about three years of age in my Discus 
tank.Unfortunately, I lost one last week.Most of my Apistos reach about two 
years of age.
The cardinals and Rummy nose tetras in the Discus tank are almost five years 
old now.
I'll gradually lower the Temp. in the ram breeding tank back to around 80~81 
F.
On the sexing part:I think the sex in some Apistogramma species could be 
determined even earlier around 3-4 weeks in species eg. cacatuoides. Others 
like A.sp.Rio Marmore were impossible for me to sex even after several month 
of age.
IMHO you could make out the sexual differences in A.cacatuoides juveniles at 
probably three weeks of age(hatching time not included that would be four 
weeks of age). If you look at some of the close-up pictures in the fry 
development album you can see the sexual differences like the pointed or 
rounded dorsal anal fin tips and the black stripes in the ventrals at an age 
closer to three weeks.I might be wrong though.I didn't look at the juveniles 
under a microscope like Roemer probably did.This are just my humble 
observations through the camera lens.
