When I first got my fish, I tried a few different varieties of fish food to find out which ones would be more effective. When I tried TetraColor Tropical Fish Flakes I thought they would enhance the color of the aquarium like the container suggested. It did not, but that was okay. My fish ate the food and seemed content. The flakes break up easily and the container stores well with a screw on lid. The flakes did however, make the tank seem dirtier. The flakes that were not eaten floated to the bottom and after several days, my tank needed cleaned. The food did not smell too horribly bad, but the pieces were large except at the bottom of the container. Overall I was satisfied with the flakes as well as with other Tetra products and I am likely to purchase them again in the future. The flakes claimed to use natural ingredients which is a plus in order to keep the fish healthy. I also liked that the flakes can be used with a large variety of fish types, even ones that are not tropical. I used the food to feed all of my fish since I have different kinds all in one tank.
