Ocean Nutrition Formula Two™ Pellets are a soft and moist slow-sinking food formulated using fresh seafood, spirulina (blue-green algae), kelp, and garlic. This blend of ingredients results in a food with an appropriate protein content for all herbivorous (plant-eating) and omnivorous (plant and meat-eating) marine tropical fish. They provide daily nutrition, support color, and promote growth. The inclusion of garlic creates an appealing flavor that even the most finicky fish cannot resist. These pellets are ideal for herbivorous fish because the soft and moist nature makes them highly palatable and easy to digest. Fish that eat Formula Two Pellets produce less waste in your aquarium. Reward your fish with the food they deserve and feed them Ocean Nutrition!Available in Small (+/- 1.2mm), Medium (+/- 3.1mm), and XL (+/- 8mm) pellet sizes. Use the small for fish up to four inches, the medium for fish four inches to twelve inches, and the XL for fish twelve inches and larger.
