New black leopard wrasse. What should I feed?

[Gavind3]

Hi everyone, I went to my local fish store yesterday. I went in looking for a new fish and got a wrasse. I found a certain species that looked cool. There was 4 in the tank and the other 3 were on the sand bed.  He was swimming around. I asked to feed the tank live brine and he ate so I asked for him. I was told it was a dusky wrasse. I went home and posted it on a forum and found it was a black leopard. I did research and apparently they are hard to keep. I have gotten other fish on frozen like a past copperband. This tank is 3 1/2 years old. It’s a 42 gallon reef. Yesterday I put him into the tank he actually stayed out instead of instantly burying itself like my past yellow corris wrasse. He stayed up for an hour after the lights turned off. This morning he wasn’t out but I went to the gym and came back and he was out to my surprise. Today I feed frozen mysis and brine mixed with api general cure and focus. Everyone ate but the new black leopard wrasse. He ate a couple pieces but spit them out. I see him hunting for pods. What should I feed him?
