I know there are some that do just fish only without the live rock and was wondering what your maintenance is like. Rarely when you see the massive tanks in restaurants and public aquariums do you see live rock, worms, and snails, etc. Typically it's artificial corals and large fish. While I love all the critters and variation that comes with live rock in a smaller tank, I think if we eventually set up a large fish only tank I would prefer it to have less variables to deal with.
