i seen a show where they were showing Convict Tangs. they showed how the female will sprint up about 20 ft and broadcast her eggs, then a group of males would be right behind her to broadcast their sperm. the main reason i believe theres currently no Tangs being captive breed is they need so much space to spawn. i have heard that some huge aquarium has had Tangs successfully spawn, but i have not seen any documented reports. would be cool to know the details if it did happen.
