all that in the same tank?
I agree with Firefighter, the oscar wouldn't do good in a small tank like that, let alone those tankmates.
you do have a few problems with your setup though. first is the amount of fish in your tank. at mature sizes (assuming they get there), your tank is going to be extremely overstocked. the koi alone is going to get up to 18" and should not be kept in tanks IMHO.
second, you have tropical and coldwater fish coexisting. that can only lead to problems down the line with whichever fish is in the wrong conditions.
my advice would be to find a suitable home for the koi (a large pond) and get a larger tank (30 gallon or larger would be great) for your fish. check garage sales, I regular see 50 gallon tanks (with stand, lights, filter and accessories) for less than $50. just keep an eye out and force yourself to wake up early on saturday mornings!
