Herbivores will eat only plant materials. They consume large quantities of algae and other plants each day. They need to be almost constantly grazing and to reflect this, food should always be available. Frayed plants should be removed before they start decaying and rotting in the water. Herbivores like to eat peas, zucchini, lettuce, cucumber, marrow, potato, spinach and aquatic plants.
Herbivores shouldering be fed three or four times daily.
