According to the National Wildlife Federation, clownfish eat bits of leftover fish that are caught by the sea anemone. The clownfish also gobbles down little pests that try to live among the anemone’s tentacles, and they chase away the butterfish and other anemone enemies that can eat the tentacles without getting stung.Know More
Clownfish are also referred to as anemone fish because they live alongside the sea anemone. The pair have a symbiotic relationship because the anemone protects the clownfish from predators while picking up nutrients from the clownfish's excrements. The sea anemone contains tentacles that sting and capture fish. The clownfish is immune to the tentacles because they are covered in a layer of mucus that prevents the anemone from stinging them. Other items on the clownfish diet include small zooplankton, algae and even the tentacles of the host anemone.
Clownfish range in size from 3.9 inches long to up to 7.1 inches long. They are yellow, orange or even red in color, and they can have white bars or patches. These fish are native to the warmer waters of the Indian and Pacific oceans, and they can most often be found in places such as the Great Barrier Reef and the Red Sea.
