Coral Placement for the Long Haul

Placing corals requires strategy and specific technique before and after the coral purchase. Relying on putting SPS up high and softies/LPS down low leaves your tank looking predictable and boring. My coral selection for the long haul talk shows you not only which corals to pick, but also where to put them in your tank to create a mixed reef tank worthy of any tank of the month award.
