the life of the lumpfish

The lumpfish lives a symbiotic life and often is referred to as a ‘cleaner’ fish, finding most of its food in the form of parasites that live on or near the bottom of the sea or on other fish such as salmon. The fastidious lumpfish will diligently nibble its meal off rocks or swim alongside an infected fish, picking off sea lice and other parasites. A single lumpsucker can eat over one hundred sea lice in the course of a meal.
