Once again....I am not claiming that Scarlets (or any other food) is the best, has the best ingredients, or is the most nutritious. OP asked for recommendations for food that would increase color and pearl which Scarlets Dark Rise and Endless Red do a great job of.
Astaxanthin does appear to be the only red color enhancing ingredient, but just because two different foods has it, does not mean they are equal as the amount of the ingredient can vary greatly.
I agree with you that as hobbyists we can not detect everything that is going on with our fish. But let me ask you this......if my fish live long, seemingly healthy lives (which they do), and your fish live long, seemingly healthy lives, what's the difference?
I am not claiming that anyone "needs" both staple foods and grooming foods. There are people that feed nothing but NLS, there are those that feed nothing but foods marketed for Flowerhorn, and there are those who don't feed pellets at all. I am am not trying to push the way I do things on anyone. All I have done is offer a recommendation based off my own personal experience and results.
Who says that "Hikari is the best food among cheap foods"? I personally use Hikari (Saki Deep Red & Saki Growth).
Excalibur has foods with higher protien (which I use) but what do you think of the ingredients in their Diamond Dust or Intense Red that have 41% and 42% (Hikari Bio Gold has 45%) protien?
Is NLS a great food? Yes! Is it the best overall food on the market? Might be! Is it as effective in increasing color, pearls, or head as some of the other foods? Nope!
