hwchoy said:yesterday I just learn something new, from a biologist hor. apparently for some livebearers such as platies (or mollies, I couldn't remember), the males just have to rubba the female, and that will trigger ovulation and which can mature into fries, without having any sperm from the male injected! of course the babies are all clones of the mommy lah.
U sure? can mature to fries meh? dunno :dunno:
but i did read that the one time sperm injection to the female guppy can last her for a few mths and also enought to fertilise a few batches of eggs... ;p
