Jebb's Mushroom Coral (Cantharellus jebbi) – Complete Care Guide

General Information

Cantharellus jebbi, commonly known as Jebb's Mushroom Coral, is a rare and unique coral species highly sought after by advanced reef aquarists. Its striking appearance, resembling a mushroom cap, makes it a standout addition to any reef tank. This coral is part of the Fungiidae family, known for their solitary and free-living nature. Unlike many corals, Cantharellus jebbi does not form colonies, instead existing as a single polyp with a fleshy, disk-like structure.

Native to the Indo-Pacific region, particularly around deep reef slopes, this coral is adapted to low-light environments and moderate water flow. Its rarity in the aquarium trade is due to its specific habitat requirements and the difficulty in sourcing it sustainably. Hobbyists prize C. jebbi not only for its aesthetic appeal but also for the challenge it presents in terms of care and maintenance.

Care

Jebb's Mushroom Coral is best suited for experienced aquarists due to its specific care requirements. It thrives in aquariums with stable water parameters and a mature biological system. Placement in the bottom or middle of the tank, away from direct high-intensity lighting, is ideal to mimic its natural habitat. This coral prefers moderate water flow, which helps keep detritus off its surface without causing tissue damage.

While C. jebbi is photosynthetic, it benefits from supplemental feeding of small particulate foods like phytoplankton or marine snow. Regular target feeding can enhance its growth and coloration. Maintaining stable water conditions, including proper calcium and alkalinity levels, is crucial for its health.

Diet and Feeding

As a photosynthetic coral, C. jebbi derives much of its energy from its symbiotic zooxanthellae. However, it also captures nutrients from the water column. Target feeding with fine particulate foods such as phytoplankton, rotifers, or marine snow can support its nutritional needs and promote growth. Feeding once or twice a week is sufficient, ensuring that the coral is not overfed, which can lead to water quality issues.

Behavior and Compatibility

Cantharellus jebbi is a peaceful coral that does not exhibit aggressive behaviors like sweeper tentacles. It can coexist with other non-aggressive corals and reef-safe invertebrates. However, care should be taken to provide adequate space around it, as its fleshy tissue can be sensitive to contact with other corals or rockwork.

This coral is best kept in a dedicated reef tank with compatible tank mates, such as small, peaceful fish and invertebrates. Avoid placing it near aggressive corals or species that may disturb its placement.

Health and Common Issues

Maintaining stable water parameters is critical for the health of C. jebbi. It is sensitive to fluctuations in temperature, salinity, and pH, which can lead to stress and tissue recession. Regular monitoring and maintenance of water quality are essential to prevent issues like bleaching or infections.

When selecting a specimen, look for a coral with vibrant coloration and no signs of tissue damage or bleaching. Acclimate it slowly to your tank to minimize stress. Routine care includes gentle cleaning to remove detritus and ensuring that it is not overshadowed by other tank inhabitants.

Habitat

In the wild, Cantharellus jebbi is found in the Indo-Pacific region, particularly on deep reef slopes and sandy substrates. It thrives in low-light environments with moderate water flow, where it can anchor itself securely. Replicating these conditions in captivity is key to its success.

Conservation Status

Due to its rarity and specific habitat requirements, C. jebbi is not commonly collected for the aquarium trade. Sustainable practices and captive propagation are encouraged to protect wild populations. Hobbyists should ensure that their specimens are sourced responsibly, avoiding any negative impact on natural ecosystems.
