TIP from FNM: Herbivorous Fish Feeding Habit

Herbivores are on the opposite end of the dietary food chain from carnivores. Although herbivores can sometimes be seen eating live foods, the proper diet for herbivores comprises of plants, algae and fruits. Examples are octocinclus catfish, sucker fish (plecostomus), black Molly and snails.

They have no true stomach, instead they have a specialised intestine that is capable of breaking down plant matter. Their teeth are flat, which allows them to grind food before swallowing it. Due to their lack of stomach to hold large volumes of food, they must eat frequently, at least several times per day. As they are required to feed frequently, they are not the best choice for a community tank. 

Herbivores require a diet of all or mostly vegetable matter. True herbivores do not have a large stomach and hence, have to eat more frequently. These fish are primarily vegetarian, and should be fed accordingly.
