Oscar havoc

In my 125 g I have two Oscars that were supposedly raised together. They are about three years old. The tiger, Cali, has become super aggressive towards the red, Hu. Nightly, Cali cleans a large circle then tries to round up her "mate." Hu wants no part of it so then this horrible chase begins. It ends when Hu is all beat up and I interrupt it. They are now separated. Last night at 2 am, Cali broke through the divider. What a hussy.

I feel it best to re-home one of them which is breaking my heart. They are both beautiful but Hu is more laid back so I am thinking I will keep it. I'm asking my lfs to find a good home for one of them. They will make sure the buyer has the appropriate size tank.

Can I assume that Cali is a female? Which sex clears the nest?

If I remember with my Managuense, it was the that moved the objects, but I also remember the female cleaning the rocks that she was going to lay the eggs on.

Did you mean the male moved the rocks? Thanks a lot!

Both sexes prepare the spawning site. Since they haven't spawned in 3 years, chances are they're the same sex. Since females will often spawn together, it's most likely you have two males. One is preparing the site and waiting for a female, so the other one has to leave. Nothing is certain though. That's just conjecture from experience.

That is the scenario I am leaning towards. After rehoming the red Oscar, will the tiger who is the aggressive one be a aggressive with any other non-Oscar fish I put in the tank?

Your guess is as good as mine, and I've kept and bred Oscars for a long time. Even if they're not ready to breed you wouldn't know for sure till you try it...
