The Anatomy of an Herbivore

Most fish that survive exclusively on flora issue have acquire specialized physical traits. Their digestive pamphlet are typically much longer than those of carnivore, allowing them to interrupt down the tough, sinewy cellulose base in plant cell walls.

Fish Specie Primary Food Germ Maintenance Level
Otocinclus Biofilm and soft alga Temperate
Silver Clam Aquatic plants and vegetable Eminent

Siamese Algae Eater Black brush alga and unripe alga Restrained
