personally i like a fish only tank with live rock. i had a coral tank, but to me, there too much maintanence, because a lot of things can be bad for them. a fish only tank gives u the advantage of lower lighting, which is cheaper. corals are really nice if u know what ur doing, and if u have the time and knowledge. fish need work and time too though. most zoo's and mushrooms dont require high intencity lighting, but they will still need quality lighting. corals will rule out fish such as butterflies, box fish, puffers, and other aggressive fish because they will most likely make a meal of corals. the only down side to a fish tank imo is ick, which is seen quite often, and become a pain in the as$. thats my 2 cents, and im sure ppl with reef tanks will say do a reef tank, but imo a fish tank with live rock and some shrimp and snails and hermits is a lot of fun
