Just make sure that you feed your fish with a fairly wide variety of different things (I think you are doing pretty good) and be sure that you are not feeding your fish too many fats and carbs in comparison to proteins, as this can cause fatty degeneration of the internal organs. FDIO takes a slow course and does not show many--if any--outward signs, but is, in the end, fatal. It is one of the greatest causes of death in aquarium fishes, and, unfortunately, apparently not well known to many aquarists.
