Common name: Peacock's Tail

General information

Padina pavonica, commonly known as Peacock's Tail, is a brown alga found in the shallow subtidal zones of temperate seas. It is easily recognizable by its fan-shaped thalli and concentric, calcified rings that resemble the tail feathers of a peacock. This alga is not just an aesthetic addition to the aquarium but also plays a role in nutrient cycling and can be an indicator of water quality.

Care

Peacock's Tail requires moderate to high lighting to thrive in a reef aquarium. It prefers moderate water flow that mimics its natural habitat, where it can receive nutrients and dispose of waste efficiently. This alga can be a good competitor against nuisance algae, as it can utilize excess nutrients in the water, helping to maintain a balanced ecosystem.

Symbiosis

While Padina pavonica does not have the same kind of symbiotic relationships as corals or anemones, it does provide a habitat and food source for a variety of marine life. Small invertebrates may take refuge among its fronds, and herbivorous fish might graze on it.

Habitat

Peacock's Tail is typically found in the Mediterranean Sea and along the Atlantic coasts of Europe and Africa. It inhabits rocky substrates in the shallow subtidal zone, often forming dense mats that can be quite extensive. In the aquarium, it should be anchored to a solid surface where it can spread and grow.
