It’s not anything special. I just got the hikari angelfish food and I don’t like it. It just falls apart leaving only the worms for my fish to eat. SFB Angel and Butterfly works a lot better for me. I’m sure there are better brands but hikari and SFB are available and relatively cheap. Then I feed two sizes of mysis every other meal and the occasional Marine Cuisine. Next they get two sheets of nori a day. I have a big foxface that eats a ton of it so I need to give two.
Finally if I have more natural food I give it that. Sponges are my favorites but caulerpa, and even corals that are overgrowing. Just trying to give a good variety.
