ok, first off, welcome to the board. Second, how long has the tank been set up for, and are you cycling it? Also, what do you have for sand, how much? and do you have any live rock in there yet? if so how much? if not..are you planning on getting any? What kind of a tank do you want to have, reef, fish only or fish with live rock? There is a wide variety of fish that will go nicely into your size tank. Is there anything that you like inparticular? also, remember that many fish need to go into a tank that is stable and mature, so dont rush into anything yet. Go slow, ask questions here, and good luck.
