I have two angelfish and the white female spawns every 10 days or so. yes she is young and restless! the question is about the black one. it acts like a male and uses its breeding tube to fertilize the eggs, or at least it appears so. the eggs usually gets eaten by other fish in the tank by the next day, so I can never tell whether the eggs are really fertilized or not. Only thing I am sure of, is that most eggs are not white after 24 hours.
this way I cannot tell whether the black one is male or female.
I then try to sex it by its breeding tube. Well it is as big as the other female's, not really pointed. the only thing it does differently, is that when it "fertilize" the eggs, the tip of the breeding tube is sort of vibrating. The other female doesn't do that.
Based on this can the black one be a male? If I don't get a positive answer I guess the only way to find out is to let them spawn on a slate and keep the slate in a safe tank to see if they hatch.
Thanks for helping me...
