All fish in our tanks expend much less energy than they do in the wild. The difference in the nutritional requirements of all the different species fish is CRAZY. Those requirements even change depending on the environment of a single species. THEN there's changes that occur with age. We will never be able to hit every single fish with the perfect diet, as these prepared foods are developed for the general population.
Hmm I wonder why the spend less energy? In a large tank with adequate flow it seems like they would have the same behavior as they do in the wild.
