Query: Fish wouldnt touch it

I have a 45 gallon tank with 7 cichlids for varying colors in it. I bought this from a local store because it appears to be made specifically for my fish. My fish never ate a single piece of this food. I feed my fish once in the morning and once at night. The food always floated at the top of the tank and would eventually break down turning the water reddish though the food promises to be a clear water formula. I ended up throwing the entire container away. I wouldn't use it again.
