It is going to be a complicated process. I only have this male. I got 10 in the group but it looks like 5 males and more may develop. The only problem is I have the mother she is 2 years old I see only one definite female out of the group and she is just about 2.5 to 2.75 inches so that leaves me with 2 females. The other 2 males are about 2.75 inches and the rest are very small about 2.5 inches and smaller and one of them is a 100% male. The kicker is I dont know if any of the other 9 are dragon jakes they just might be a crappy strain of AER or a yellow/orange dragon strain. They have no red in the anal fin, only the mom has a slight touch of red in her anal fin. She has a White colored body and her fry the other 8 juvies have a yellow/orangish body color and no red in the anal fin. The other males just might turn out not to have the dragon gene. Only time will tell what they are going to develop into. So I only have this male to work with. If I'm lucky I can get the mom to breed with her son and get the only sibling female to breed with him.
