[Old Yeller Tang]

If your tank is very established then you don't need to feed as often. Mine open up every night, so I know good things must be floating in the water and I do feed my tank with phytoplankton at night. When I do feed them, I like using the frozen invert food because it is a more fine matter that sprays nicely over the polyps and makes it more difficult for my cleaners and fire shrimp to pull out and trust me, they're waiting on the wayside.
