I'm currently on an sps kick, specifically millepora. I love the pics of the rainbow tenuis, but I know those only exist in blue lights and photoshop. With millepora, I'm focusing on corals that pop from across the room. From the super orange milleporas to the deep reds and greens, they're the ones that will make or break a tank. Throw in the special ones too, but you need the stark contrasts of deep single color or bicolor corals. They're the ones that bring you in. To the trained hobbyist, an acro with 5 colors may interest you, but to the everyday "Is that rock a coral?" guy, these are the eye catchers.
