Hi, new to the forum. I’ve been keeping African cichlids for over 15 years. I’ve made the decision to switch to South American cichlids. I’m so far thinking of 1 Red Oscar, 1 Green Terror and a couple of Acaras. Ive done some research, I know how big theses guys get and temperament. Any input would be greatly appreciated. I also do 50% water changes weekly.

Setup:
90g, Ehheim Pro3 Ultra G160 and Fluval FX6 filters, Hydor Koralia 3G Powerhead, Hydor ETH300 inline heater, led lighting, pool filter sand and various river rocks.

Welcome!
You will probably have to double up on wc once they get some size on them. But test and see.

That setup will be mighty shortb on room as the fish grow. Depending on what kind of acara may end up with one pairing up with the gt.

For a 90g I would suggest either a solo Oscar, Solo GT, or a community Acura tank. While it would work out when small. Start adding size and adulthood to the mix and all bets are off.

Forgot to mention, they would be all males, and would be all added together as juveniles.

Beside the territorial issues with fish that get as large as you suggest, as they grow water quality will become problematic in that size tank, and to keep water quality up as adults, you will need to do almost daily water changes (oscars being the major polluter).
I consider a 90 too small for 1 oscar, with no other fish.
The acaras would work, maybe even the GT, but they are very close cousins so territorial issues may arise even if they are all males..
I have a 180 gal with Andinoacara coerleopunctatus (Panamanian Acaras (or G.T.s depending on how you look at it)), my alpha male took exception to, and killed 2 other similar size males when they were put in together.
But now he is calm with about a dozen females, smattered with some indistinguishable subordinate males.
