Best known for being featured in the movies “Finding Nemo” and “Finding Dory,” the clownfish has become a popular aquarium pet. Nemo and his dad, Marlin, are ocellaris clownfish, also called false clownfish or clown anemonefish. Anemonefish are so-named for the sea anemones in which they make their homes. There are 28 species of anemonefish, and they come in many colors, such as pink, red, yellow, black, brown and multi-colored stripes.
Size & description
Most false clownfish are orange with three white bands on the head and body. The white bands are outlined in black. Their bodies are a bit more than 3 inches (88 millimeters) long on average, but they may grow up to 4 inches (110 mm), according to the Animal Diversity Web (ADW). The tail is rounded and the dorsal fin is lined with 11 spines.
False clownfish live in the coral reefs off the coasts of Australia and Southeast Asia as far north as southern Japan. They are found mainly around certain kinds of anemones, a creature that anchors itself to the sea floor and uses its tentacles to attract food. The anemone’s tentacles have stinging cells called nematocysts that release a toxin when prey or predator touches it.
