   Hello Roger. I would advise against this for several obvious reasons. First   
   of all, while you haven't stated the size of your tank, both oscars and   
   kois grow to a rather large size, particularly the koi. Koi may be okay   
   in a typical home aquarium while they are young juveniles, but once they   
   begin to grow towards maturity, you will either need a very large tank, or   
   preferably an outdoor pond.   
      
   However, that is not the only reason why I am making this suggestion. A   
   second reason is that oscars, once grown, can become very pugnacious,   
   aggressive fish, and may not enjoy sharing their tank with another fish   
   which it views as either a threat, or as an intruder in its own territory. I   
   don't know exactly which species of koi you have, but in most cases, I   
   would think that the koi will eventually outgrow the oscar.   
      
   Another reason why I would question this kind of mix, is due to the water   
   parameters that are required by each fish. Oscars are tropical fish, while   
   koi are not. Furthermore, in their natural habitat, oscars prefer soft,   
   acidic water, such as you will find in many peat-laden rivers and lakes of   
   tropical Latin American countries. Koi, on the other hand, can probably   
   endure very cold climates, such as you find in more northern latitudes.   
      
   One area where you will probably find some agreement is in their feeding   
   habits in an enclosed environment, such as a home aquarium. I would   
   think that they would both greatly enjoy Hikari pellets.   
      
   Anyway, it is obviously your decision, but that is my two cents worth for   
   your consideration.
