Ed, I'm more than capable of giving an objective non biased analysis of any food product, and I have been thus far, hence the reason why I suggested looking into buying directly from a feed mill. I didn't once even suggest that you must, or even should, feed NLS to your fish.
But in order for you to accept my assistance you must first decide whether you live in a world where a fish should receive its protein from marine protein, or rice krispies. Once you have made that decision it will be much easier for me to assist you further.
Yes, 7 posts in you finally mentioned the actual products that you feed, but I didn't skim over them, Ed. I've been in this game a long time, and it isn't like I haven't used other foods, or that I'm not familiar with the overall quality of most of them, including the various products that Ken sells.
I "know" this Ed, because I've been doing this a long time, and if it walks like a duck, quacks like a duck, and craps like a duck, that's because it's a duck.
Some carbs/starch in a food are fine, as previously mentioned wheat flour is used as a binding agent, but when I see carbs, followed by more carbs, followed by more starch, red flags go up. Stating that the gluten could come from corn wasn't clever on my part, it made sense in keeping how I view the rest of Kens products, and the types of ingredients used, and if you actually scroll down on Kens "food sticks" page, you'll see that
corn gluten is actually listed in the Cichlid Sticks, the Premium 5 Stick Blend, the Premium Tropical Sticks, and the Premium Brine Shrimp Sticks.
Keep in mind those are some of his Primo formulas .....
Speaking of which, how does one refer to a food as Premium
Earthworm Sticks, when "earthworms" are the 11th ingredient listed by weight?
As previously stated, some carbohydrate in a food is fine, it can serve a purpose beyond a binding agent, and if used in limited quantities the vast majority of tropical species will be able to assimilate a good portion of the nutrients. But there's a HUGE difference between a food that uses a low inclusion rate of wheat flour as a binding agent, and one where a good portion of the crude protein is derived from grains/starch. The reason being that outside of species such as carp/koi, which can assimilate fairly hefty amounts of carbs, most tropical species cannot, and most certainly not those that fall on the carnivorous side of the equation. In simple layman terms, most fish will use some of those carbs as an immediate source of energy, and store what isn't used immediately as fat. Just as in dog food, the less carbs/starch/grain in a fish food, the better. Unless of course you prefer fat dogs, and fish.
Also, most terrestrial based plant matter comes with excessive baggage, in the form of anti-nutritional matter. Some of this can be removed via proper processing, but not all. Hence the reason why Pablo chose to use soy isolate, over soybean meal. Isolate costs a LOT more than soybean meal, but it is anti-nutrional factor free, and because it is so concentrated, one can use a lot less to get the same job done. Having said that, now that Pablo is making his own food on site, soy isolate is going to be removed from all future New Life formulas.
You can read more on Soybean meal, and some of the nutritional problems that can be associated with its use, in the following link:

The same holds true for most/all other terrestrial based plant matter.
If there's anything else that I can assist you with please don't hesitate to ask.
