Common name: Cotton Candy Nudibranch

General information

The Cotton Candy Nudibranch, scientifically known as Polyplectana kefersteinii, is a vibrant and colorful sea slug that adds a touch of whimsy to any reef aquarium. This species is part of the Phyllidiidae family and is known for its striking appearance, which resembles fluffy cotton candy. The body is typically pink with a sprinkling of yellow spots, and the mantle is adorned with tubercles that give it a unique texture.

Care

Caring for Polyplectana kefersteinii requires a well-established aquarium with plenty of live rock and a stable environment. They are sensitive to water quality, so parameters should be kept consistent, with regular water changes to maintain cleanliness. They feed on sponges, so it's essential to ensure that their dietary needs are met, which can be challenging in a home aquarium.

Reproduction

Reproduction in Polyplectana kefersteinii is not well-documented in the home aquarium, but like many nudibranchs, they are hermaphrodites, possessing both male and female reproductive organs. They typically lay eggs in a spiral ribbon, which will hatch into free-swimming larvae.

Symbiosis

While not known for any specific symbiotic relationships, nudibranchs like Polyplectana kefersteinii play a role in the ecosystem by controlling sponge populations, which can otherwise overgrow and smother corals.

Habitat

Polyplectana kefersteinii is found in the Indo-Pacific region, often in coral reef environments. They are benthic creatures, meaning they live on the bottom of the ocean, usually at depths where light can still penetrate and support the growth of their sponge prey.
