The TetraMin tropical flake fish food is the staple of my aquarium fish's diet. It is a scientifically formulated fish food that is good for all mid-water tropical fish. The flakes come in a plastic cylinder with a vacuum sealed foil top and a plastic cap. After the foil is broken, the cap snaps on with a slight twist. The cap does not hold tight to the container, so you must be careful not to knock the fish food over.
The flakes of the tropical fish food by TetraMin come in a rainbow of colors. They are very thin and easily broken, which is a positive thing. Some of the flakes are much too large for smaller fish to eat. When feeding, you must break them up by rubbing them between your fingers.
My tropical fish have maintained optimum health, color, and vitality by eating TetraMin tropical flake fish food. The food does not make the water cloudy when fed normally.
