Mine will eat just about everything i give them... The only veggies I provide is Formula 2, which they gobble right down. That that some garlic in it too.
Otherwise i'll feed them mysis, Brine Shrimp + (which has tons of good stuff like clams, squid etc.), and on occasion they'll get some dainichi pellets. Also, about once or twice a month i'll mix their food up with fresh crushed garlic. They find that yummy.
