Corals signal to Gobies,"Come clean me." -- Olivea Varady

The goby fish and Acropora Nasuta Coral are found in Fiji. The Goby fish is gray with brown blotches. The Goby fish likes to live in the Acropora Nasuta Coral. The Goby fish does not get to live in the coral for free though. The Goby fish and the coral make a deal. The deal is that the Goby fish has to eat the toxic seaweed and the Goby gets to live in the coral. Toxic seaweed is seaweed that will overproduce and make the coral sick.
