Well, I would love to have a HUGE tank, however, I have a townhouse and space is limited so the 55 is the winner for me. I'm gonna keep the 36 I have as well, so that should be enough to keep me busy. This is what I've done so far. I have ordered 70lbs of live rock, a sump Wet/dry filter, and a protien skimmer. I have a HOB filter that I can add to the sump if I see I need it. Can I buy replacement bulbs for the canopy lights that come with the tank that will be sufficeint for coral and anemones? Do you think what I've mentioned will be sufficient?
