Carnivore
meat eaters, generally requiring live foods
have a short intestinal tract, and a relatively large stomach designed to hold an entire fish. Their digestive system lacks the ability to digest vegetable matter, so even though they might eat plants, they cannot derive nutrients from them as other fish do. Because they will chase down and eat other fish in the aquarium, carnivores are not suitable for a community tank.
Omnivore
eat a variety of meat and vegetable matter. Although omnivores can and will eat vegetable matter, they cannot digest some types of grains and plants. Their teeth and digestive tract possesses some of the traits of both the carnivore and the herbivore. Omnivores are the easiest of all fish to feed, as they eat flake foods as well as live foods, and everything in between. For that reason, omnivores are an excellent choice for a community tank.
Herbivore
Herbivore
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 an herbivore consists of plants, algae, and fruits. They have no true stomach; instead they possess a specialized intestine that is capable of breaking down plant matter. Their teeth are flat, which allows them to grind food before swallowing it. Because they lack a stomach for holding large volumes of food, the herbivore must eat frequently - at least several times per day. Because herbivores require frequent feedings of vegetables and fruits, they are often not the best choice for a community tank.
Any heterotrophic organism that feeds (consumes) exclusively on plant matter.
