sera marine Spirulina Grazer XL Nature is a veggie food without dyes and preservatives for mainly herbivorous fish, such as tangs, angels, and wrasses. The carefully manufactured tabs serve as bottom or stick-on tabs, allowing many other fish species to feed as well and observing even shy fish while feeding.
The high amount of spirulina algae with plenty of mineral and vital substances supports healthy digestion, color development and health.
Since the tabs keep their shape for a long time, they also allow for feeding slowly without polluting the water.
