Will they breed in the furture

[Oscarluva]

Hi I got 2 oscars from different stores on the same day. They won't leave each others side. I saw that one of them ( in the back corner ) got larger in the stomach. I am wondering is it possible that it's pregnant and that they will be a breeding pair. I have 70 gallon aquarium. Any advise

Thanks

At smaller sizes oscars group together for protection. It could be that (and it's more likely that).

You'll just have to wait and see...

If you are hoping for a breeding pair I would obviously advise you to NOT put anything else in the tank with them. With a 75 you have to be careful with two anyway, not due to bioload so much (as long as you have good filters) but due to territory issues.

Good luck with them.

Oscars don't reach sexual maturity until they are around 2 years old which puts them around the 9-12in mark. Judging by those pics you have a long way to go. Even if by chance you have and male and female that doesn't guarantee they will pair and breed, I've heard of males killing females and vice versa. The best way is to get six fish let them pair off and rehome the rest but that requires a much larger tank. Even my breeding pair continually test each other around breeding time.
