I checked out the ingredients lists on extreme and compared it to NLS. It seems Xtreme uses basic meals that most other fish food manufaturers use which are comprised of mostly leftovers. NLS uses the WHOLE animal in its meals. Ex: Whole antarctic krill, whole herring meal and even whole wheat flour... Xtreme also lacks the use of vegtable and fruit extracts NLS contains and garlic which is GREAT for your fish. Xtreme fish foods also has alot of plant matter(starch). Why they list wheat middlings, wheat, and wheat flour is kinda weird... included in plant matter is also dehulled soybean meal, distillers dried grains with soluables, and brewers dried yeast (all in their top 10 ingredients). In NLS it only lists whole wheat flour and ginseng along with the vegtable and fruit extracts as plant derived ingredients... I don't think you can count ginseng and fruit and vegtable extracts as fillers/binders...
Here's the ingredient list I found for Xtreme Aquatic Foods:
Krill Meal, Fish Meal, Wheat Middlings, Wheat, Shrimp Meal, Dehulled Soybean Meal, Wheat Flour, Distillers Dried Grains with Soluables, Brewers Dried Yeast, Spirulina, Monosodium Phosphate, Paprika, Limestone, Xanthophyll, Fish Oil, Lecithin, Salt, Vitamin A Acetate, Vitamin D3 Supplement, di-Alph Tocopheryl Acetate(Vitamin E Supplement), Vitamin B12 Supplement, Riboflavin, Niacin, Caldium Pantothenate, Menadione Sodium Bisulfite Complex(source of Vitamin K activity), Folic Acid, Thiamine Mononitrate, Pyridoxine Hydrochloride, Biotin, Manganese Proteinate, Zinc Proteinate, Copper Proteinate, Calcium Iodate, Iron Proteinate, Cobalt Proteinate, Calcium Carbonate, Sodium Selenite, L-Ascorbyl-2-Polyphosphate (source of Vitamin C), Canthaxanthin, Astaxanthin, Beta Carotene Guaranteed Analysis: Protein 38% min, Fat 5% min, Fiber 4.5% max, Moisture 10% max.
Compare it to a bottle of NLS Thera-a I got right in front of me:
Whole Antarctic Krill Meal, Whole Herring MEal, Whole Wheat Flour, Algae Meal, garlic, Beta Carotene, Spirulina, Vegtable and Fruit Extracts, Ginseng, Vitamin A Acetate, DL Alphatocophero (E), D-Activated Animal-Sterol (D3), Vitamin B12 Supplement, Niacin, Folic Acid, Biotin, Thiamine, Riboflavin Supplement, Pyridoxine Hydrochloride, Calcium Pantothenate, L-Ascorby-2-Polyphosphate (StableC), Choline Chloride, Ethylenediamine dihydroiodide, Cobalt Sulfate, Maganese Sulfate, Ferrous Sulfate.
Heres an excerpt from a site I googled about xtreme fish foods:
"What prevents me from classifying this as a "great" food is the use of fish meal (as opposed to a named fish, such as "Salmon Meal") and the absence of the word "whole" (as in "Whole Fish Meal"). An ideal food would consist of meal comprised of the whole fish, with that fish being identified. Absence of the word "whole" and without the type of fish identified, it can be safely assumed that the "fish meal" used in the manufacture of this food are the scraps left over after the remainder of the fish has been processed for other uses. In other words, the "fish meal" consists primarily (and potentially exclusively) of scales, skins, and bones. In addition, the ingredient list follows a practice known as product splitting, with three different wheat products listed. When combined, "wheat" may very well be the primary ingredient."
On the plus side people who have used it for the most part like it. Like most fish foods some fish like it/love it while others don't take to it so readily. Souds all right but I think ill stick to NLS which for me works and works very well.
