The coral reef is a complex ecosystem and it fascinates us and many scientists for years. Recent research in the Caribbean shows that fish urine is very important for the coral. Urine from fish delivers phosphor necessary for the corals to grow. Fish also provide corals with nitrogen when they breathe through their gills.
