They like it between 16°C and 35°C best but they are a few that live in cooler water.
The Arctic Ocean is too cold for coral reefs.The coral reefs cannot grow under cold conditions. They can only grow in waters between the arctic circle and the equator. They must grow under neutral tepurature water. Even if they are too hot they can't grow.

To survive, coral reefs need algae, sunlight, clear clean water, warm temperatures, and saltwater. The sunlight helps the algae grow. Coral is sensitive to dirty, cold, and polluted waters and function best when the water is clean and warm.
Living coral must remain relatively close to the surface of the water so that the symbiotic algae can have access to sunshine. The algae requires sunshine in order to complete photosynthesis which provides oxygen to the coral.
Manatees can live in both fresh and salt water, as well as brackish. If a manatee is in salt too long though, it must find other waters temporarily.
Seaweed do not have to live in water all the time - think of inter-tidal periods when they are not in the water. Only some kinds of moss live in the water. Many kinds of mosses never live in the water - but do tend to live in a damp environment. The underlying concept to think about is dessication.
You must be thinking of the Beluga Whale. They live in the Arctic Ocean.
The biotic factors of the ocean must be able to breath under water. Things like whales,fish,turtles,seaweed,and krill all live under the ocean .There can be plants too like seaweed.
Most true corals are from the tropics, and so are adapted to be in water between 75F-82F.
Because of a seahorse's enormous penis, it has the ability to shoot webs from its testes. In a Spiderman-esque fasion, it swings from ocean to ocean eating its prey and urinating on their offspring afterwards. The seahorse is truly an animal to be fearful of.
If your water is acid, coral may be of use in buffering the acid since it is alkaline. Otherwise it could well be detrimental. Coral must be properly cleaned before being placed in a freshwater tank.
Tuna are exclusively marine (saltwater) fish. They live in the ocean.
