| Care Description | Hammer corals are an iconic large polyp stony coral (LPS) that has been a staple in the hobby for generations. They are found all throughout the Pacific reefs and come in a variety of colors and growth forms. Hammer corals sometimes grow in a wall formation while other hammers grow in a branching formation. Either variety makes an excellent show piece coral for a reef aquarium however the branching varieties tend to grow more quickly. Please see below for additional care tips for hammer corals. |

General Description
Hammer corals, a type of large polyp stony coral (LPS), are iconic reef inhabitants that have been popular in the aquarium hobby for generations. They can be found across Pacific reefs and showcase a variety of colors and growth forms, with some hammers growing in wall formations while others in branching structures.
Demands and Hardiness
Hammer corals, including the Branching Neon Green Frammer strain, are relatively hardy and adaptable in a well-maintained reef aquarium setup. They do not require intense lighting, thrive in moderate to strong water flow, and can feed on small critters and pellets. While these corals predominantly depend on photosynthesis for nutrition, they also benefit from occasional direct feeding.
Lighting
In terms of lighting, Hammers, Torches, and Frogspawn varieties do not demand high-intensity illumination and can thrive under normal output fluorescents. However, placing them under stronger lighting might enhance their coloration and growth, making them even more visually striking.
Water Flow
Moderate to strong water movement is essential for Hammer corals to thrive, contributing to their health and aesthetic appeal. These corals are known for their graceful swaying movements in the currents, which is both beneficial for their well-being and visually pleasing for aquarium enthusiasts.
Feeding
Hammer corals, like other LPS, primarily rely on their zooxanthellae for nutrition, but they can also benefit from direct feeding. While they are not as aggressive feeders compared to some other coral types, they can consume Mysis Shrimp, small critters, and appropriately sized pellets in the range of 6 to 13mm.
Propagation
Hammer corals have been successfully propagated in captivity and show promise for aquaculture efforts. Although they do not grow as rapidly as certain stony corals, branching varieties are more conducive to propagation compared to wall formations. Achieving sustainable harvests through aquaculture initiatives is a potential goal for the future.
Localization & Habitat
Hammer corals inhabit tropical waters across the Pacific region, commonly sourced from areas such as Fiji, Tonga, the Solomon Islands, and the Great Barrier Reef. They are significant components of Indo-Pacific reefs, adding to the biodiversity and beauty of these marine ecosystems.
