two ways of breeding goldfish:
1)raise the temperature 78-80.....wAIT FOR THE female to be ripen with eggs....When the male is ready for breeding, tubicles(white spots) form along the edges of the fins and gills......The male will chase the female...Eggs will be disperse and the male will squirt.......
2) The "stripping" method...Squeeze the sides of the stomach of both the male and female sides....Gently exerting pressure towards the outside vents, pushing out the eggs and sperm.........Swirl the mixture for fertilizing................
