In a saltwater tank, is more preferable that the fish have more free, open space to swim, or better that there are lots of hiding places, tunnels, etc.
Or is this a matter of preference?
Depends on what fish. Smaller and vulnerable fish need lots of hiding spots. Your bigger fish such as tangs will prefer lots of room with lots of available grazing area. Its best to try and balance the tank out to give it a bit of both.
