Is sand or gravel better for cichlids? I use both & understand either is ok.
Changing the gravel color before the fish goes in shouldn't have any effects on the fish other than making it's colors a bit darker.
As for sand vs gravel, Oscars are diggers so as long as the substrate isn't sharp, either should be fine. Decorations to consider: should be large enough that the fish can't move them and if layered, won't collapse when the fish moves the substrate it's sitting on. Live plants may be tough to keep as they are notorious for digging up plants.
