Introduction to Zoanthids

Zoanthids are one of the most popular corals in the reef-keeping hobby, admired for their vibrant, fluorescent colors and rapid growth. These soft corals form colonial mats of individual polyps, creating stunning carpets of color that can quickly transform reef aquariums. Popular varieties like “Rastas,” “Eagle Eyes,” and “Pandoras” showcase the incredible range of patterns and hues Zoanthids have to offer, making them a favorite among hobbyists of all experience levels.

Zoanthids are often grouped with their close relatives, Palythoa. While similar in appearance, Palythoa species tend to have larger polyps and thicker mat formations. A key distinction is the potential production of palytoxin, a potent toxin found in some Palythoa and Zoanthid species. This toxin can be harmful to humans and pets, so handling these corals with care is essential. Always wear gloves and eye protection when working with them, and avoid exposing them to high heat, which can release toxins into the air.

Known for their adaptability, Zoanthids thrive in a variety of tank setups. Their ability to grow quickly and form colorful colonies makes them an excellent choice for adding visual interest and texture to your reef.

Description

Location

These soft corals are found in shallow reef environments throughout the Indo-Pacific region, including areas near Indonesia, Fiji, and the Great Barrier Reef. They typically inhabit rocky outcrops, reef flats, and lagoonal zones where water movement is moderate, and lighting is plentiful.

These colonial polyps attach themselves to hard substrates such as rocks, rubble, or dead coral skeletons, creating dense mats or carpets. In their natural habitat, Zoanthids contribute to the biodiversity of the reef, offering shelter and surface area for small reef inhabitants like shrimp, crabs, and gobies.

Size & Care Requirements

Water Chemistry

Zoanthids are relatively hardy and adaptable, making them an excellent choice for a wide range of reef systems. Maintaining stable water parameters ensures their health and vibrant coloration:

  • Calcium: 380-450 ppm
  • Alkalinity: 8-9.5 dKH
  • Magnesium: 1250-1350 ppm
  • Nitrates: 5-15 ppm
  • Phosphates: <0.10 ppm
  • Temperature: 75-80°F
  • Salinity: 1.024-1.026

Although Zoanthids can tolerate minor parameter fluctuations better than some corals, stability is key to their long-term success. Regular testing and adjustments will help maintain ideal conditions for their growth and color retention.

Lighting

Zoanthids thrive under a wide range of lighting conditions, with an ideal PAR range of 75-150. Some varieties can handle high light and tend to display even brighter colors under these conditions. However, most Zoanthids require a slow transition to higher light to prevent stress or bleaching. Moderate lighting is typically sufficient to enhance their vibrant hues and support steady growth.

Water Flow

Zoanthids prefer moderate, indirect water flow that keeps debris from settling on their polyps while delivering nutrients to support their health and growth. This level of flow allows them to remain open and fully extended without being subjected to excessive movement that could cause stress.
