Common name: Fan Sponge

General information

The Fan Sponge, scientifically known as Agelas flabelliformis, is a fascinating species of sponge found in the marine environment. This sponge is notable for its fan-like shape and intricate network of channels and pores that facilitate the flow of water through its body, allowing it to filter feed on microscopic plankton and organic particles. The structure of Agelas flabelliformis is supported by a skeleton made up of spongin fibers and silica spicules, which give it both flexibility and strength.

Care

In the aquarium, Agelas flabelliformis requires a well-established system with stable water conditions and moderate to strong water flow to mimic its natural habitat. It is important to provide this sponge with plenty of dissolved organic matter and fine particulate food, as it is a filter feeder. Care should be taken to avoid exposing the sponge to air, as trapped air bubbles can be fatal.

Reproduction

Sponges like Agelas flabelliformis reproduce both sexually and asexually. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs within other sponges. Asexually, sponges can regenerate from fragments or produce buds that detach and grow into new individuals.

Symbiosis

Agelas flabelliformis does not have any well-known symbiotic relationships that are of particular interest to the aquarium hobby, but it plays a crucial role in the ecosystem as a filter feeder, helping to maintain water quality.

Habitat

This species is typically found in tropical and subtropical regions, often on reef slopes and walls where it can take advantage of the water flow for feeding. It is usually located at depths ranging from shallow waters to several tens of meters deep.
