HELP Goldfish breeding!?

First of, they are the same species (Carassius auratus) and will successfully breed, however I have no clue what the fry will look like. Look for more breeding tubercles as time goes on, and feed them something special like bloodworms or brine shrimp. Once he has more tubercules he'll be able to use them to stimulate her to release eggs. Also, she should be over 3" long before she will be receptive.
