There are many species of fish that are essentially herbivorous but they will still eat the occasional bit of live food. The ones that are only algae eaters are the main true herbivores and that includes the fish that have sucker like mouths for grating algae off things eg. Plecostomous sp. Some of the ones that are mainly herbivores are the Silver Dollars "Metynnis sp. who are close relations of the renowned carnivore the Piranha. The Mollys are also classed as vegetarians but they too will enjoy a meal of brine shrimp etc.
