What to feed clownfish?

[Ruth]

Matt when I feed mysis shrimp I thaw out the little cubes on a piece of paper towel and then rinse it in RODI water before mixing with some tank water to feed. I have read that there may be phosphates and other preservatives that they use when freezing this stuff that can build up in your tank over time. I don't know if it's true but why take a chance.
