Herbivorous plecos need food containing 10 % wood for digestion, the exact amount these wafers contain.
As these novel wafers do not dissolve in water, they do not pollute the water, thereby giving shy fish the opportunity to feed in peace later.
The sinking wafers contain energy-providing wheat germ in addition to spirulina and vegetable matter.
Does not cloud the water. Dermatologically testet.
Caution: Not all plecos are herbivore (plant/algae eating)! The best known example is the zebra pleco (Hypancistrus zebra). It likes to feed on blood worms and can thus be classified under carnivore (flesh-eating).
