Platinum Marine Pellets are a complete pet food for fish. Formulated to include key ingredients to support the immune system and maximise health and condition. Incorporating all the high quality nutrition of our principal Marine Pellet, our Platinum Marine Pellets also include key dietary components designed to support the immune system and maximise health and condition. See our PLATINUM MARINE FEEDING STRATEGY for more details. Each of our pellet diets are soft for ease of digestion and designed to sink slowly in water. This is to encourage a natural feeding experience for fish.
