When I got my first package, I was like, "It's a pellet food, what's up with that?" I was expecting flakes along the lines of flake food for tropical fish. I drop it in, watch it sink, notice a few shrimp come over to it, and then I go about my business with a few other tanks. About 5 minutes later I look back, and go, "OK, now I get it. It's an exploding snowball masking as a pellet." Neat trick. I'll have to show my kids the next time I feed it. Most of my colonies polish off a stick or so within 2 days. The neos seem to take a bit longer, but they like it just as well.
