Other: a cheap flake food to keep thier bellies full, and then fresh foods, such as veggies, fruits and seafoodat least once a week(I aim for 2 or more times a week)to give them the nutritional values they need. I refuse to belive any one food item will give a proper diet, so I offer my fishes 5 (although when I run put of a food it is sometimes less) or more different food items.
