More questions. How do oscars act when matting? When the male fertilizes the eggs how in the world do they keep the water from washing the fertilizeation away? Afterwards of being fertilized. How many days does it take for the eggs to hacth?
Well I need to remove the babies from the tank? So they dont get eattion?

liplocking and cleaning the slate are two common rituals in spawning...
afterwards, the female will stick the eggs at the slate and male will
follow thereby fertilizing the eggs. the eggs should change colors into
opaque or brownish and will hatch 3 days later. its a hit and miss
chance that parents will not eat eggs or wigglers...

by any chance, how big is your tank? and how many fish do you have?

What species of fish? For two Oscars, 75g would be dangerously small. Two Oscars plus 4 other fish, that size will kill them all.

no no only the male and female well be in the 70g tank. The others well stay in the 50g tank. Then Ill most likly sale the other 4. then once the babies are big enough I put them into the 50g. Then sale the babies.

Well that work? A 70g tank is all I can afford.

Don't you need lots of space for an Oscar pair? So if they do mate, there will be enough room for the fry, and for the oscars themselves. I know that my tank wouldnt be able to have an oscar pair and babies, and its 100Gallons. And I know im pushing it by having two oscars in it right now..

What is the smallest sized tank you could put fry in?

If eggs touched air (removed from tank) don't they die and not hatch? Or do they have to be left out of the water or dried out?

they need to stay wet, but a quick in-and-out won't hurt the eggs.

The trouble with a smaller tank is the maintenance, and aggression troubles. Daily water changes won't be optional. Even a pair may feel a bit cramped, and may fight. But you might be ok.

Getting them to pair off in a 75 will also be truly difficult. Adult oscars are large, and they need to be adults to pair off. I don't see this working very well, I'm afraid. They'll start attacking each other long before a pair appears - if they don't die from poor water quality. I don't know how much filtration and how many water changes you'd need to even consider managing this water.

Fry in a 55 will be ok for a time, but it depends how big they have to be before you sell them. A pair can have a few hundred babies, and a few hundred little oscars (even just one hundred, even fifty) will be quite cramped in a 55 long before they reach an inch big. I'd say a 55 is about as small as I would go for any number of fry. If you have just three, or five, smaller may be ok with lots of water changes for a short time.

I'm worried, have you taken into account that for each oscar tank, you'll need at least two filters that can filter your water at 10x the total water volume each hour (say it's a 55 gallon, your filters need to do 550 gallons per hour). Also, heaters, and good quality food. Daily, or more than daily water changes are also costly. Breeding fish is not cheap, if there isn't money for a big tank, it seems unlikely that all this will be an easy matter financially.

Breeding fish is a fantastic venture. I've never tried with oscars, but I have bred my malawi fish many times. Watching your fry grow and flourish, and go off to new homes is quite an adventure. So please, don't let me put you off. It might just be worth saving a bit longer for this one.
