Size/length?

[tang daddy]

if you have a choice of tank lengths I would opt for the 4ft instead of 3ft.
While your fish list is considerably small atleast if you have the choice to get larger fish in the future without setting up another tank.

I see that you don't want a sump which is fine however you could easily incorporate a sump into your stand which then you could go with a fairly decent skimmer like the euro reef or an asm. Otherwise you spend the money on a better skimmer like a tunze or if you skimp on one like a coralife you will most likely end up with saltwater on your floor as the water in your display fluctuates up and down.

I wish my small house could accomadate larger tanks like a 6ft however 4ft is fine for me now.
