unfortunately all of them died in the 10th day, except one that is 6-7 months old now. you can read the story in a thread called "my oscars fry" in oscar section. I was inexperienced in feeding the fry and couldn't hatch the brine shrimps well. also the water quality was not good enough.
but now in the new spawn I have saved about +700 of them till now and they are 24 days old.
