Sometimes, less is more. Sometimes? Most of the times.
When you follow the evolution of most reef tanks, they seem to achieve a point where they seem to look at their best early on, and from that moment on, it’s down the hill. The main reason that causes the tanks to loose their “freshness” is that empty space shrinks. Not only corals grow, but we also keep putting more corals and or rock inside. We also get tired of looking at the same layout, but I won’t get into that issue.
Aquariums need open space. This empty space is needed aesthetically and the fish will thank you too.
So, let’s say your tank is in its early ages and you only have half a dozen corals. Don’t spread them all over the tank. The same goes with rock. Take the opportunity and create contrasts: areas filled with corals and areas completely empty.
Empty spaces also make your tank look clean, whether those spaces are sand or uncovered back glass.
Corals that most of the times are placed on the sand shouldn’t be placed like islands. They should always be placed right next to a rock, so they are an extension of the rockwork. This helps to preserve open spaces in the sand.
And rules are meant to be broken. You should have a good reason break them, though.
