Common name: Dead Man's Fingers

General Information

The Alcyonium palmatum, commonly known as Dead Man's Fingers or Mediterranean Sea Fingers, is a captivating soft coral found in the northeastern Atlantic Ocean and the Mediterranean Sea. This species is named for its unique appearance, resembling the fingers of a hand, and is a popular choice among hobbyists looking to add a touch of the unusual to their reef aquariums. Unlike many hard corals, Alcyonium palmatum does not have a rigid calcium carbonate skeleton, making it more flexible and able to sway with the currents.

In the wild, Dead Man's Fingers play a significant role in the ecosystem by providing habitat and shelter for a variety of marine life. In captivity, they serve as a fascinating addition to reef tanks and can help educate aquarists about the diversity of coral species and their ecological importance.

Care

Alcyonium palmatum is considered a moderately easy coral to care for, making it suitable for hobbyists with some experience. They thrive in aquariums that mimic their natural environment, with moderate water flow and lighting. Providing a stable environment with consistent water parameters is crucial for their health.

These corals should be placed in areas of the tank where they can receive gentle to moderate water flow, allowing them to sway naturally. This not only mimics their natural habitat but also helps them with nutrient uptake.

Diet and Feeding

While Alcyonium palmatum is photosynthetic, it benefits from supplemental feeding. In the wild, they capture planktonic food particles from the water column. In captivity, feeding them with fine particulate foods like phytoplankton or specialized coral foods can enhance their growth and coloration.

Behavior and Compatibility

Dead Man's Fingers are peaceful corals and can coexist with a wide variety of other reef inhabitants. They do not exhibit aggressive behaviors, making them compatible with other corals and fish. However, it is important to ensure they have enough space to prevent any competition for light and nutrients.

Health and Common Issues

Alcyonium palmatum is generally hardy but can be susceptible to changes in water quality. Maintaining stable water parameters and regular monitoring for signs of stress, such as retracted polyps or discoloration, can help keep them healthy. Regular water changes and good filtration are recommended to prevent common issues like algae overgrowth, which can smother the coral.

Habitat

In the wild, Alcyonium palmatum is found attached to rocky substrates in areas with moderate to strong water movement. They are typically found at depths ranging from shallow waters to about 50 meters. Their natural habitat includes temperate reef environments where they contribute to the structural complexity of the ecosystem.
