I agree...decorate with rocks unless you feel like replanting then every couple of days...Also, if you are going to eventually add new fish to your tank with your oscars, the sooner the better! My 12 inch oscar recently got a pleco, and won't leave him alone. I'm about to redecorate the the tank and hope it helps. He's been practically alone all of his life, he's had a few small fish in with him other than feeders when he himself was small, but he eventually ate them.
Try to keep a variety of diet because once they learn to prefer something, it's very hard to get them to eat anything else. Pellets have lots of good nutrients and feeders help them grow quickly. I prefer Hikari Cichlid Gold pellets, they don't shred or cloud the water, and they are great for the color of the fish!
Good Luck and congrats on your new family members! They will develop lots of personality!
