i have a brown female estherae too! ,(it came from a wildcaught and f1 breeding) i too have a nice strain of electric yellows , sorry , i still don't know if this brown female estherae is gonna throw orange female babies,..we'll see,..she's just a baby (about 2 years old and didn't hold well the last spawn),..hopefully as she gets older she'll fiqure it out. (she held for about only a few hours (i watched the spawning) and then she spat all her eggs out , and i had the "pleasure" of watching some of the other tank inhabitants eat the eggs, before she tried to "re-pick-them up" (she spat the eggs to shuffle them instead of keeping them in her mouth) she did this 2 or 3 times before the other fish became aware of a "free meal" i've heard of this problem, but have never experienced it personnally before,
