My cuc keep my tank completely algae free with the exception of coralline algae, and the nori disintegrates before my kole tang eats much of it. A friend told me he fed algae wafers for his tangs and cuc, and I had to try it out of curiosity. My fish are going to town on it. My kole is eating it much better than he does the nori...who knew? Is there any reason, I may not be aware of, that I shouldn't supplement their diets with these? The main ingredient is spirulina.
