Explanation:

Sunlight - Corals rarely develop in water deeper than 165 feet (50 meters). Corals depend on the zooxanthellae (algae) that grow and since these algae need sunlight to survive, corals also need sunlight to survive.
Clear water - Corals need clear water that lets sunlight through i.e less turbidity.
Warm water temperature - Corals generally live in water temperatures of 68–90° F or 20–32° C.
Clean water - Corals are sensitive to pollution and sediments.
Saltwater - Corals don‘t live in areas where rivers drain fresh water into the ocean. They need saltwater.
