TetraMin Tropical Flakes is a dry flake food built around Tetra's Clean and Clear Water Formula, which is designed to be highly digestible and to avoid leaching color into aquarium water. The flakes are made with a proprietary ProCare blend of immunostimulants, vitamins, biotin and omega-3 fatty acids intended to support fish resistance to everyday stress. An Active Life Formula adds antioxidants for cell health, select proteins to support growth and prebiotics to aid digestion. Each container holds dry flake food only; no additional equipment or assembly is required. Owners feed the flakes directly into the aquarium, offering only as much as fish can consume within a few minutes, two to three times a day. Containers are resealable to help keep the flakes fresh between feedings.
