Common name: Bush coral

General information

The Birdsnest Coral, Seriatopora caliendrum, is a small polyp stony (SPS) coral known for its delicate, needle-like branches and vibrant coloration, ranging from pink to purple hues. It is a popular choice among reef aquarium enthusiasts due to its rapid growth rate and the intricate, tree-like structures it forms, which can add significant visual interest and complexity to a reef aquascape.

Care

Birdsnest Coral is considered to be of moderate difficulty to keep, which makes it a suitable choice for intermediate to advanced reef keepers. It thrives under high lighting conditions provided by metal halides, T5s, or LED systems. Strong, intermittent water flow is also crucial to prevent detritus from settling on its branches and to promote nutrient exchange. Stable water parameters are essential, with particular attention to maintaining calcium, alkalinity, and magnesium levels to support its skeletal growth.

Symbiosis

While Seriatopora caliendrum does not have any specific symbiotic relationships akin to clownfish and anemones, its structure provides shelter and hunting grounds for small reef fish and invertebrates. It can also be a part of a diverse reef community, contributing to the overall health and stability of the ecosystem.

Habitat

In the wild, Birdsnest Coral is typically found in shallow reef environments with strong water movement, often in the Indo-Pacific region. It is commonly seen at depths ranging from just below the surface to about 30 meters, where it receives ample sunlight to fuel its symbiotic algae, zooxanthellae, which live within its tissue and provide the coral with energy through photosynthesis.
