Convict tang not eating

[ThrillYa]

I've had this convict tang for about a week. He started picking at my live rock right away but I can't get him to eat anything I offer. He's losing weight fairly quickly.

I've offered:
frozen mysis shrimp
formula 1 flakes
broccoli
leaf lettuce
some calurpa from refugium
live brine shrimp

What should I try next?

my purple tang he is a pig. its good to feed tangs greens becuase there herbivores... although mine doesnt know hes an herbivore, he eats tons of mysis when i feed it..... i got mine to start eating a few types of macroalgae at the lfs, get some that tangs are known to eat, try a few diff types, put it in the tank where the tang will see it.... leave it

this is how i got mine to start eating, now he eats spirulina flakes, algae sheets.... and i still feed him macro, the tang has even started eating hair algae.... sporadically.
