Pea Gravel will not work with any cichlids.. they prefer fine sand or aragonite.
In a 75 gallon tank, an Oscar can't really have any tankmates. A single tiger oscar will fully stock the tank.
Oscars, I've read, get 14-18 inches, which is way too big to be in a 18 inch wide tank (which is what a 75 is), imo.I'm not familiar with needle nose gar. Oscars are actually South American and tend to do well if not overcrowded. They will typically eat any fish that will fit in their mouth though. Pictus cats may not be safe with and oscar. In a 75 the oscar should be fine but you are limited on tank mates. Anything large enough to not eventually become lunch would probably overload the tank. Maybe a small school of silver dollars or single catfish that gets to the 10-12" range.
