Hi, I was wondering and wanted opinions on how just one big oscar would do with other non-Cichlid fish like tinfoils, bala shark, 1 ft. catfish, 2 silver dollars, leporinus fasciatus, Distichodus? I know Cichlids can be aggressive when in pairs especially some Cichlids. Since Oscars are not generally excessivly aggressive I was wondering since there will be only one if it could get along with these others? Thanks
