Peer pressure can make this clownfish change its stripes

Tomato clownfish, like the one seen here nestled in a sea anemone, lose all but one of their white stripes (the head bar) as they grow up.

Tomato clownfish, in response to an unpredictable world, appear capable of adjusting when they lose their stripes based on cues from other fish and their habitat, a new study in PLOS Biology finds.
