Oscar female!

I just found out my Oscar is a female!0o
How big of a tank to breed?55g?
Do they need to be a certain size to breed?

Gonna need at least a 120g to breed. A 4' tank is just not large enough for full grown breeding O's.

I've been breeding oscars for decades and I can't tell(I could not even tell my pairs until the females tube dropped) and I'll go further to say that anyone who claims to be able to sex a oscar visually is full of kaka. The only way to properly sex a oscar with a 100% certaintly is to watch them lay eggs for females and fertilize eggs for males.

Oscars do not reach sexual maturity until around 12-16 months on average which puts them around 9-10". I always used a 75g for when the oscars when they were ready to spawn then they were moved back into a 150g when the deed was done. Even with a pair in a 75g was a huge amount of effort, this required 2-3 50% weekly water changes to keep the nitrates below 20ppm.

Did she lay eggs? Did the breeding tube drop? Venting is still not 100% for oscars.

I don't think there is a definate way to tell on OSCARS. I have 4 of them, the only way I knew is watching the females actually laying the eggs...
