For larger marine fish, we have developed Hikari Marine A. The spongy texture of the pellets mimics the food these fish eat in the wild. This food contains algae, pure cultured spirulina, and Omega-3 fatty acids, making it suitable for both herbivorous and omnivorous species. The addition of mussel extract makes even the pickiest eaters eager for this color-enhancing food. Before feeding Hikari Marine to your fish, you can soak it for a few minutes in pure fresh water. The water aids digestion, leaving more energy for enhanced color. – Daily food for large marine fish. – Easily digestible and less waste. – Contains pure spirulina for fantastic colors
