Which one is better if i want a reef tank?? It would be cheaper with the 40b because of shorter lights.
don't go by price go by what you like. in my opinion, if you are on a very limited budget, it will be very difficult to keep a reef. you must have some start up money. and do it right. just one quick advise from experience you will always want a bigger tank so go as big as you can!
Remember that most of the fish in the store require a 6' tank.
