Ive got six oscars around 9 inch in a six ft tank

[aceguerra]

Also have about 15 other cichlids in there They seem to co habitat
My question is What climate can I put them in as I think two have paired off?

I think you're lucky this setup has worked this long. That is a lot of aggressive fish for even a 6 foot tank. I am assuming its 150 or 180 Gallons?

To play it safe, you would probably want to keep only a few Oscars and look into rehoming a good portion of those aggressive cichlids...especially the Dovii, Jaguar and Flowerhorn. I've seen Dovii's get up to 20 inches and attack anything in the tank. Jaguars, Devils and Flowerhorns can do similar.

If your intention is to breed the mated pair, I would remove most of the other cichlids and maybe just keep the convicts and/or Jack.
