Oscar food: guppies or ghost shrimp?

Crayfish is the natural diet of an Oscar. Guppies or Ghost Shrimp are way too little to do them any good. A better solution would be to grab some plain raw frozen crayfish at the store and feed those. They love em'!
 
Thanks for all the info guys.

I am planning to let the oscar live alone, in the biggest tank that will fit that empty spot in the living room, probably 60-80 gallons.

I'm pretty paranoid of catching food from the wild. Parasites and diseases scare me... o.O

I've never thought about peas. I'll plant some peas this spring to replace my tomatoes, which I'm having horrible luck with anyway...

After some research, another possibility is maybe mealworms? Some articles say they're a good source of protein.
 
I only feed my oscar hakari gold pellets.
 
Mealworms are good source of protein for animals capable of digesting chitin, the hard outer shell. They're very fatty as well and are usually recommended as occasional treats.
