Oscar Fry

[kaiso232]

I have a pair of young Oscars that have produced two sets of eggs.After three days they eat all of the eggs. On the second occasion they started to eat the eggs again. I managed to get about 50 eggs out of the aqarium. Whar are my chances of raising them and secondly what do I do to stop the parents from eating the eggs

Welcome to the Fabulous AC!
Usually oscars are great parents,until the fry are free swimming.
Were the eggs fertalized before you removed them?

The best thing to do would be to have the eggs laid on a peice of slate.You take out the slate with eggs and place it in another cycled tank on an angle with a bubble stone to release bubbles gently around the eggs.
You should then add some methylene blue to the water until it turns dark blue. This is used to help prevent and treat fungus on eggs. Keep the temperature at a constant level until the eggs hatch. After a while, the fry will fall of the rock, when they have all fallen off, remove the slate. Once the yoke sack has disappeared, you can start feeding them. You can now transfer the fry into their own tank now. This is now the crucial part of breeding Oscars. The tank doesn't have to be very big, 10 or 15 gallons will suffice. If you put them in a tank that is too large, they will not be able to find their food easily enough.

They need feeding a lot and they need to be fed the correct food. If you do neither of these, they will die very quickly.

Fresh hatched brine shrimp is about the starter food food for them.

Yep, just keep the eggs in clean water with enough O2 around them.
fresh water also works if you can't provide cycled tank. actually in hatching eggs there has been no difference between cycled and fresh water for me.

usually people add methylene blue to prevent fungus, I don't and I never had a problem. however, it depends on the water and tank conditions I think.

if they have been fertilized they will hatch after about 72 hours. then after 3-5 days they start free swimming and feeding should be started ( newly hatched brine shrimp is best )

for the parents I don't know a way but letting them do it on their own and hopefully after some tries they will figure it out. otherwise you have to separate the eggs or the male.
