For herbivore aquarium fish, DR. BASSLEER BIOFISH FOOD GREEN is a high-quality granulated food. In addition to the essential healthy nutrients, it also includes 5% ground leaves of the "miracle tree" Moringa oleifera and 5% of the priceless freshwater algae Chlorella. Carotenoids, antioxidants, essential non-saturated amino acids, chlorophyll, vitamins, and trace elements are all abundant in this food. In healthy conditions, ornamental fish will grow quickly and exhibit their natural colors with this well-balanced diet. The granulate sizes of DR. BASSLEER BIOFISH FOOD GREEN are M, L, XL, XXL, and 3XL. All three water zones receive nutrients because the granulates in the smaller pellet size M sink gradually. This provides bottom feeders, fish in the middle zone, and surface feeders.
