Rapps may find that Xtreme works better for him as he is an importer, and most fish (especialy wild caught) will accept a softer grain/starch laced food much easier over a more dense/hard food such as NLS. So for freshly imported fish (wild caught or not) a food such as NLS that doesn't absorb water as readily as a starch laden food, that is more difficult to chew/swallow, there will be more chewing involved, hence a greater mess.
While I have done a good bit of reading (not that I think I'm a nutrition expert), I've payed a lot more attention to aquaculture and science studies than forums. But personal testing and comparison has formed my fish food preferences over anything else, and I've been doing that for years, now. I do pay attention to ingredients (which can vary according to product, with some companies more than others), pay less attention to opinions on forums, which are often contradictory and less often objective, and pay the most attention to what I've seen in my own tanks with my own fish over years of testing and comparing.but what do we have other than the labels and these forums?
NLS makes a wafer, has algae, alfalfa, and spirulina in it, though they aren't the first ingredients (first two ingredients are herring and krill). I put one in my tanks for my plecos about once a week. My tanks get either plenty of sun and/or have plenty of driftwood (for algae, etc. to grow on). Started doing this mainly for my L200 green phantom plecos, which don't seem to eat regular flakes or pellets much, not like other plecos I have (or have had). They actually seem to do well just eating algae that grows, but this way I feel better that they're not missing any nutrients they might need.^ And none of that is nearly as depressing as reading the ingredients in most algae wafers.

Yeah, this wet weight theory that seems to be making the rounds lately, seems to have started with food reviews on one particular forum as far as I can tell and a lot of people seem to have taken that as gospel and run with it. Don't know where that reviewer got his theories on this, but now this notion is getting around the forum circuit. The same reviewer rates some foods highly, which I know from years of personal experience and testing are inferior to some others he rates lower.Only a complete moron would even consider paying the freight on frozen "wet" Antarctic Krill, when it is already processed in to a much much much lighter "dry" meal on board of the same ships that are harvesting that krill in the AntarcticOcean. Ditto to wet Herring, vs Herring meal. In both cases the raw ingredients are collected & processed when in a whole state, but they are also processed into a powder before being sold.
Same thing with 'color enhancers'. Any good fish food will have nutrients that naturally are color enhancers. Any fish in the wild or in a tank would be hurting if it didn't get these same natural nutrients.BTW - there is no such thing as a fish food that is "hormone free", unless that food contains zero fish products, as all fish contain natural growth hormones. New Life containers state "No added Hormones", which is more accurate.
LOL... ok... just shows how things can get out of hand... now half the foods on the market, including NLS, are being accused of wet weight ingredients chicanery.It actually started with me, several yrs ago after what the owner of Omega stated about their processing method, and the fact that Omega does use "wet" processing waste as their main protein source. I believe that at some point over the years kmuda read my comment, then used it in his food reviews. Of course it was all pure speculation on my part, I can't say with any certainty what any manufacturer does behind closed doors.
All ingredients are required to be listed in order of predominance by weight. The weights of ingredients are determined as they are added in the formulation, including their inherent water content. This latter fact is important when evaluating relative quantity claims, especially when ingredients of different moisture contents are compared.
For example, one pet food may list "meat" as its first ingredient, and "corn" as the second ingredient. The manufacturer doesn't hesitate to point out that its competitor lists "corn" first ("meat meal" is second), suggesting the competitor's product has less animal-source protein than its own. However, meat is very high in moisture (approximately 75% water). On the other hand, water and fat are removed from meat meal, so it is only 10% moisture (what's left is mostly protein and minerals). If we could compare both products on a dry matter basis (mathematically "remove" the water from both ingredients), one could see that the second product had more animal-source protein from meat meal than the first product had from meat, even though the ingredient list suggests otherwise.
