What fish are found in a reef?

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.
