Common name: Serpent coral

General information

Pachyseris rugosa, commonly known as Rugose Cactus Coral or Rugosa Coral, is a species of hard coral that is appreciated for its unique texture and form in the reef aquarium. This coral is characterized by its leafy or plate-like appearance, with a rough, wrinkled surface that resembles the folds of a cactus. The coloration of Pachyseris rugosa can vary from shades of green to brown, often with lighter tips, which can add a striking contrast to the reef aquascape.

Care

Rugose Cactus Coral is considered to be a moderately easy coral to keep, making it suitable for intermediate-level hobbyists. It thrives in moderate to high lighting conditions and requires moderate water flow to prevent sediment accumulation on its surface. It is important to provide stable water parameters and maintain calcium, alkalinity, and magnesium levels to support its skeletal growth.

Symbiosis

While Pachyseris rugosa does not have any well-known symbiotic relationships like those seen in clownfish and anemones, it does host a variety of microfauna in its complex structure. These small organisms can include copepods and amphipods, which contribute to the biodiversity of the reef tank.

Habitat

Pachyseris rugosa is found in the Indo-Pacific region, typically in shallow reef environments. It is often seen growing on reef slopes and overhangs where it can receive ample light while being protected from strong currents. In the wild, it can be found at varying depths, usually between 5 to 20 meters, where it forms part of the reef structure and provides habitat for other marine organisms.
