This question has nothing to do with me, but if you had 2 Os for a while, and u decide to get 2 or 3 more(in a big enough tank of course) how would they react with eachother? i know it depends on the fish and how it may and may not, but i was just curious

Until you try, you just won't know. Obviously if a couple of them have been there for a while, they may not look favourable upon any other Oscar encroaching into their environment. There is a possibility that you introduce a female and you already have a male, they may well pair up. O's have got an aggressive side but I certainly wouldn't class them as the most aggressive cichlid I have ever come across

alrit thanks, i just kinda thought that the group already there would stay to themselves and the new group would stay to themselves but i just wanted to see wat others thought too, thanxs for the answer

presently, i have 4 oscars (after losing BlackStripe). they used to be together
at the 110 gal tank. as they grew up, bullying, liplocking, and thrashing becomes
a daily occurrence. so i decided to parted them away. i had to moved Survivor and
PinHole at the 90 gal tank. Unfortunately, the did not get along well, thus, i
removed PinHole to give time for Survivor to heal. Lately, i move OneEyeJack to
where Survivor is, and there is no issue yet for two weeks now. same is true with
Glutton and PinHole.

wow, they r just like people, they get along and dont get along with certain Os lol

yeah they are....see those body scrape..... they were injury when fighting.


hopefully, they will paired up...no fighting yet for two weeks now

i have lost fish doing exactly that. i have added fish of the same breed and had very bad fights to the point one has died from the injury's. when you think things have settled down trouble can flare up again. I can't answer why, its just the fish attitude i guess. i am in the same position now. I have had a oscar many yrs (6-7+yrs)and it has never been any trouble. Not one fight. i added a arowana and the oscar didn't like it. after a few days they made friends and all was well. then i got up one morning to find the oscars mouth damaged. I am now considering I may need to put down the oscar cos the damaged mouth. you just will not know until you try, and be willing to remove 1 to a new home if things don't work out.
