Ocean Nutrition Angel Formula

[Aquattro]

I have a Queen Angel that doesn't get any special Angel formula and seems to do quite well. Most the angel foods I looked at really didn't have much in the way of sponge anyway.
From what I can find though, the Rock Beauty might require more sponge than a Queen.
What I do is look around the LFS for any rocks where sponges are growing and ask if they can scrap some off. I grow some in another tank, but seldom see my angel eat it.
Lots if spirulina, nori and mysis keeps mine happy.
