Common Clownfish

Snapshot: The common clownfish sports a stocky, oval-shaped body ablaze with brilliant orange to reddish-brown hues. Bold black lines contrast sharply with its vibrant body, with three striking white bands racing down its sides.
 
Other tidbits: Can grow up to 11cm or so. Range extends throughout the Indo-Pacific region, including Papua New Guinea, and the Great Barrier Reef. Instantly recognizable from the Finding Nemo movie, this fish is a moviestar!
 
Bare bones must know: Live-rock fish-only system, fish-only system, or reef aquarium. Best bought as a mated pair (male and female). No need for anemones to keep these clownfish happy! They thrive just fine on their own terms
