What do you feed your fish?

After reading the 'discus - possible HITH' thread, I was wondering what
others out there do to ensure a proper diet for their fish.

I buy and mix my foods. I will include a quality general mix in (small
grain), freeze dried bloodworms and a spirulina based vegetable grain in my
blend. I kept one old food container and mix equal amounts of the three.
Then I feed the mixture during feeding time. I also suppliment every other
night with sinking algae wafers for my nocturnal ones.
