I have told if u r new to saltwater/reef, its better to get the biggest tank u can get. since the smaller tank u have, the more time u need to check on the paraM.
I would take the time to start cycle the tank, and at least let the tank settle for about 6months before u add anemones, maybe more depend on your paraM.
and for corals, all the pros r helping u on the light, so I will tag alone LOL.
but as AMD told me before, the light is all depend on wt u r keeping.
maybe get a list of what u want to keep then go look for the light?
