i found this note about sex determination in a. cacatoides at the krib:
'Mike.........There's good news and bad news! The bad first.........the so-called triple red strains usually, like guppies, don't have a pattern of throwing 100% triple red young....the probable % of triple red male may run from only 10% up to as strong as the particular strain is......maybe 80%. If your male is already breeding then his colors and color patterns are probably 95% set. If the amount of red is not to your liking then wait for some of his "puppies" to grow up and keep the ones with the most red. Next problem.............a combination of high temp (75-80+) with a high pH (7.5+) will cause the % of males to be 90%(it's happened to
me)........conversly, with lower pH and temps the ratio of females will
increase.
Mike'
so it would seem to me, that if you want a decent mix of females and males, a ph slightly below 7.5, and a temp of 75 deg would be nice. does this agree with others' experiences with this fish? i would like anyone who has raised these fish, and recorded their temps and parms, and also noted the male:female ratio to chime in, if possible.
