Purina Aquamax is also about 98% digestible.....
Are we talking protein digestibility?
Total digestibility when fed an optimum amount.....Only about 2% of what goes into the front end, comes out the rear end of the fish. Overfeeding will cause more waste.
I think we all would like a competitive feed we can have quality control over, however, I seriously doubt your aquarium fish are getting all they need to grow and thrive. In a "natural" setting, the fish will ingest all manner of zooplankton and other microscopic organisms along with plant matter, soils, etc. These things contain a wide variety of nutrients, minerals and trace elements essential for health and growth that can not be replicated in an aquarium. Fat and protein are only 2 key components to growth. I wonder what the nutrient breakdown would be for all that menhaden....?
