The clownfish  on the other hand has a fascinating way of developing an immunity towards the anemones stinging tentacles.  After it is stung the clownfish returns to the anemone repeatedly, gingerly touching the tentacles to its ventral fins  and then slowly introducing its entire belly. The elaborate process helps the fish develop  a protective  mucus layer allowing it to live safely among the tentacles of the anemone. In return for shelter in its tentacles, the anemone feeds on the scraps from the clownfish’s meals without having to wait for its own prey as they are not voracious predators.
