I assume by a regular tank, you mean one which contains Freshwater Fish, such as a goldfish tank. A reef tank consists of a mixed marine environment, containing a mixture of reef fish, corals, invertebrates, and other organisms.
With respect to freshwater tanks, there are several types. Ciclid tanks, planted tanks, tropical tanks, and cold-water tanks could all be considered distinct types.
Marine tanks come in just as many varieties also. There are cold-water varieties, reef tanks, FOWLR (Fish Only With LiveRock), lagoon tanks, and many others.
Hope this helps.
