The eastern clown anemonefish lives in symbiosis with a sea anemone that has stinging and paralyzing tentacles, against which the clownfish is immune.

The anemone's tentacles provide shelter for the clownfish from predators, and in return, the clownfish protects the anemone from its predators and provides it with leftover food from its meals.

Le poisson clown doit son nom à sa coloration bariolée mêlant un orange vif à du blanc qui rappelle les couleurs des habits des clowns.
