Sorry to everyone on this post for not responding sooner, but the reasons may seem more apparent with some of the additional posts and the email that was posted which while not intended to be posted non-the-less does clarify the reason for not responding to the original question. Additionally, we had a glitch with the alert process which has now been corrected. We spend lots of time and money researching fish nutrition and developing meaningful diets. If a competitor does not have the information needed to produce a quality product it is not the job of Hikari to provide them information to improve their products. For all the additional posters here please remember one important point when it comes to ingredients. Hikari's approach to any diet formulation is to provide the best overall nutritional offering for the specific fish (species specific) which will allow them their best chance at a health filled life while reducing the waste which can adversly impact their enviroment. The relative rank of the ingredients, unless you have the actual recipe and ingredient profile in front of you, is not a good indicator of a diet's quality or composition. It is more imortant to judge the quality by the performance of that diet over time. Companies like Hikari, that invest considerable sums of money in in-the-field research, ingredient formulation and processing to optimize nutrient performance, feeding trials to verify the results meet the expectation of the diet and ongoing research to constantly improve a diet whenever possible, as well as ongoing feeding to parent fish and their offspring to judge the long term impact, have built a reputation on performance, and real nutritional science. Furthermore, the texture of the pellet is important too to help the fish take it as their primary food. Hikari was the first company in the world to develop a pan-cake-like pellet (the technology Massivore Delite utilizes) to make the product more efficient and effective when fed to these big guys because the texture is more like a live creature. The comment about carnivores not eating starch is actually not factually correct. Carnivores, like most other fishes of the wild eat a varied mix of ingredients natural to their habitat. While fish parts and crustaceans may be a larger portion of their daily intake, algaes, plants and other materials in the water are also eaten along with them. Our job at Hikari is to try to develop a diet that will help them look like they do in the wild, using ingredients that will not adversly impact their health with time. In the case of Massivore Delite(R) we have accomplished that and the look of the thousands of fish who's owners have sent us pictures reaffirms the food does what it was developed to do.
