Angels, Tangs, Butterflies, Mollies and many other freshwater and marine fish are natural 'pickers'. They graze 90% of their day picking at the surfaces of wood, corals and rock. It is important that they are offered plenty of seaweed and algae throughout the day; this will strengthen their immune system, reduce aggression and improve their overall health.
