Damselfish on coral
 
The fin fanning of damselfish in the Red Sea helps boost the rate of photosynthesis of the algae that live inside corals. We already knew that the damselfish (Dascyllus marginatus) lives in symbiosis with the coral Stylophora pistillata. The fish use coral branches as shelters and nests, and in return they remove sediment from the coral surface and excrete nutrients. But it turns out there is more to the relationship. Nur Garcia-Herrera at the Alfred-Wegener Institute in Germany and colleagues measured oxygen levels inside the branches of coral kept in tanks either with or without fish. Advertisement They found that ...
