Best Angel Food?

[splix]

I'm curious what is the best angel food now-a-days. I currently have 3 angels (regal, emperor, flame) and a moorish. Everyone eats everything offered very well except the regal is still very picky on food. He's eating but he's still on a special diet on only what he likes.
I primarily feed New Life Spectrum pellets and LRS reef or fish frenzy, cant remember which. Since trying to get the regal to eat, the tank has been fed a lot of different stuff.
Pellets - Regal loves
LRS fish food - Regal isnt a fan of
LRS fish eggs - amazing stuff. Everything goes for it
frozen mysis - hit or miss with the regal.
live brine - I need to try again since regal knows to eat
live bloodworms - regal has eaten but not very interested
clams on 1/2 shell - one thing my regal cant say no to.
Nori - regal has no interest

I noticed Brightwell Angelixir. Is it worth getting?

Skip the angelixer. Ocean Nutrition an San Francisco Bay brand each have frozen food formulated for angels and it contains sponge, which is a big part of their diets.
