My male was mature (given in exchange to my breeder) and the three females are from different batches, but the same father. As for inbreeding: At a certain point (the beginning of a breed, or in this case, color scheme) everything is inbred. That's the only way to keep getting the desirable traits. It has happened with the different breeds of dogs. I am going to do my best to keep my fry from inbreeding; I'll probably be getting another male along the line and keeping some of my female fry.
Nightowl (and anyone else who needs to know): the best way to determine if a young cacatuoides is male or female is not by color or size. All three of my females have some orange and black speckles on their tails; one of which is very colorful for female standards. When the females turn yellow to spawn, the orange gets more intense. The best way to tell a juvenile male form female is by the pectoral fins. They almost look like the fish's feet (I know I'm wierd). A female's pectoral fins always have a strip of black on the fronts of them. When they are ready to spawn, they become even more intense. The males do not have this. If anyone knows this to not be the case, let me know. But this has been foolproof so far.
