Tomato clownfish eat algae, zooplankton, and small, aquatic crustaceans.
A characteristic of all anemonefish belonging to the genus Amphiprion is that they are mutualistic with anemones. This means that they live together with large anemones, and each helps the other species. When a tomato clownfish brings food back to an anemone, the anemone is rewarded with crumbs from the meal. In turn, the fish is protected from predators while within the anemone. The anemonefish also help the anemones by cleaning and caring for them, which again benefits the anemone greatly.
