My clown pair eat well too, I try to vary their diet by mixing, matching randomly. I also have a Midas Blenny that eats the same stuff. Any leftovers go to the CUC and cleaner shrimp, and sand sifter star.

I haven't added any vitamin additives, but do have Garlic Xtreme. I rarely add that. Truthfully.. for the cost.. I'm not sure it does anything at all. You can call me skeptical.
The clowns eat just about anything. The Midas is more picky. Prefers frozen, but being such a huge pig, he'll eat flake. Once he sees the clowns pigging out and he gets into a jealous rage. ;P I probably feed too much. Pretty sure of that. But the fish are fat, happy, and have colored up immensely. I typically do 2x a day. Vary between frozen 2x, to frozen 1x and mix dry 1x. Depends on my mood, and what I happen to throw together.
When I am away for a few days or longer. I mix the various dry foods in the feeder. They do great. When I return they ravage the frozen food, so I'll only feed frozen for a few days to 'make up' for being away.
