Welcome, I'm a new kid on the block also, Lots of good info in the forums. Since your new to hobby, I'm sure your reading alot and getting alot of opinions. So here's mine.
Lots of new aquarists,don't have a good plan on where they want to be 1 yr from now,
and equipment for this hobby is expensive, so they buy things that don't give them
options for the future. 2x40watt fixtures, IMO
don't provide but minimum lighting. PC
might be a better choice for you at this point. And in the future you can still use it with with any kind of set-up you want.
