Montipora is the easier-than-Acropora SPS genus. M. capricornis (capricorn cap, plate-form), M. digitata (finger-form), M. danae, M. confusa, M. setosa, M. spongodes, M. samarensis. Encrusting, plating, and digitate growth forms cover all major reef niches.
Montipora is the standard recommendation for reef-keepers transitioning from softies/LPS to SPS. Forgiving of parameter swings, colors up under modest light (150-300 PAR), and propagates aggressively. Most Montipora species can be fragged by simply breaking off a piece - no specialized cutting required.
