1.no 2. 90000 3.yes 4.the corals is the house of the fish
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
Corals are not decomposers. They are consumers.
Corals are plants.
Hermatypic corals contain zooxanthellae (a symbiotic algae), whereas ahermatypic corals do not. It is like saying that hermatypic corals are photosynthetic, where ahermatypic corals are non photosynthetic.
Reef life is very diverse. Depending on geographic location of reef you could find several hundred types of fish. Some fish feed off the corals, some the inverts that swell on the corals, some off the fish that feed off the corals or inverts and so on and so forth. Probably close to 90% of the saltwater fish you see in a petstore came from a reef envoirment, though not all are reccomended for home aquariums with corals, because some do feed on the corals.
No, corals are not edible.
Yes, corals are composed of an exoskeleton
dynamite fishing and muro ami can destroy corals so if there are less corals, less corals will be produced.
No corals doesn't eat zooxanthellae they only eat zooplankton. Zooxanthallae helps corals to live and keeps corals colourful.They live on the coral polyps.
Many corals, specifically hermatypic corals, contain symbiotic algae that provide the coral with sugar from photosynthesis. Algae also feed zooplankton, which corals feed on. Basically, algae provide corals with food, indirectly.

There is none. Corals are cnidarians.
