As others have stated, nori is important along with mysis.

You can soak both the nori and the mysis in Selcon and add a drop of garlic juice to whet the tang's appetite.

Nori is best purchased from any supermarket for a fraction of the cost from an LFS. Just get the unsalted plain stuff used for sushi wrap.

Veg like lettuce have almost no nutritional value for herbivore marine fish. Any Oriental grocery store should have packs of nori sheets available. Mine come from a place in Chinatown, in 50 sheet packs. You can soak these in Selcon or garlic too.

Judges are still out on lettuce, though it is better than mysis. People have been feeding tangs lettuce for years and years. I did it for a couple of years and all my fish were healthy, anyways each their own. I would agree that Nori is better, Try to get spirulina flakes. If you find powdered spirulina it mixes well with a garlic/nori mush but dissipates rapidly. Flakes or pellets seem to be the best option, though again pellets sink quickly (at least the ones i've seen) and pollute if not cleaned up. Anyways from what i've read tangs feed almost exclusevly on green-blue algae (cyanobacteria/Spirulina) in the wild so i'm thinking that is defn your best bet. I also fed my tangs a lot of my prunings from various macroalgaes in my refugium. They really liked it. I had all kinds and they seemed to gobble it all up.

See if he will take formula 2, either flakes or pellets.

spirulina
 

FIRSTLY if you can get it to eat nori, that would be my first priority with any tang that needs to be rescued.
But in case you haven't received enough spirulina suggestions i feed my tangs the HBH super soft spirulina fish foods. My tangs love it and I particularly like it because the first ingredient is spirulina.

The Chevron died, got back from work and it was dead. The other tang I rescued is weird looking, I think it is a atlantic blue tang turning blue, I am not sure and will post a picture of it. I had them in seperate tanks because I was pretty sure that the other mystery tang beat up on the chevron pretty bad. I am (was) feeding both tangs nori and formula one herbivorous pellets.
I will try taking a pic tonight and post it.
Thanks for all the help, really apreciate it, sucks that he died.
