yea i couldnt do it so i ended up breeding danios then i switched to guppys because they breed so easily just get a breeding tank so it catches the babies before they get eaten and make sure to grind up fish food verysmall to feed the lil buggers and keep the fish in the breeding tank wen it is showing close to birth signs then take him out about 3 days after she has had the babys
i found a website where a guy got sucessful breeding. The rosys have to be at least 3" and need a low cave. A rise in temp triggers it. I already got like five big rosys. so i am going to give it a shot.
