I just had to share my experience with this food. It's a Marine Food, but I used it for my african cichlids.

I used all different kinds of foods. Hikari, Hagen, New Life Spectrum (NLS), Tetra, HBH etc etc etc....

I have to say, I've never been more impressed by this food. Others have told me this food is great, but just assumed it was hype (similar to the NLS hype). You can actually SMELL the difference; much better than NLS. My fish readily accepted this food, went crazy over it; I can say they never did that for NLS.

I bought it at Petco; quite expensive: $9 for 100 g.

Let me know if any others have used this food. I've also heard their formula II food is excellent.
