Adrian my broodstock praecox are still the original ones I got and a
selection of their first offspring. Based on my calculations that would
make the youngest of them at least 3 yrs old.
I try and maintain the temperature in the room a minimum of 25 deg C,
whilst at the moment the water temps are running at about 30 deg C with
a maximum of 36 so far this season.
Maybe the yellow finned female strain is longer lived!;-)
