For a number of years I have been feeding fish in my reef tank prepared food from a coral and fish food manufacturer. It is high quality stuff and certainly very easy to feed. Crack off a piece of the frozen food, mix it with some tank water and disperse it in the tank. The one problem is the cost can add up over time.
My solution was to make my own DIY homemade fish food. I picked up an inexpensive food processor and went shopping for some seafood at a local supermarket, where I found some cheap scallops, raw shrimp, and mussels. I then walked over to a Petco next door and bought some cubed mysis shrimp, blood worms, krill and silversides.
Other ingredients ordered over the internet included the following:
Vita Chem (the whole bottle)
Spirulina Powder (1 tbsp)
Kent Garlic Extreme (1/2 bottle)
Reef Roids (1 tbsp)
Several sheets of Nori
RO/DI water (1 cup) MORE
