Common name: Yellow Sponge

General information

Cliona carteri, commonly known as the Yellow Sponge, is a species of demosponge found in various reef environments. This sponge is known for its bright yellow coloration and its ability to bore into calcium carbonate substrates, including live coral and limestone. It is a filter feeder, drawing water through its body to extract nutrients.

Care

Yellow Sponges are relatively hardy and can be a unique addition to a reef aquarium. They require stable water conditions with good water flow to facilitate their filter-feeding habits. It is important to ensure that they are not smothered by sediment or algae, as this can inhibit their ability to feed and respire.

Reproduction

Reproduction in Cliona carteri can occur both sexually and asexually. Sexual reproduction involves the release of gametes into the water column, while asexual reproduction can occur through budding. In the aquarium, sexual reproduction is less common, but hobbyists may observe small buds forming on the parent sponge.

Symbiosis

Cliona carteri has an interesting relationship with the reef environment. While it can be detrimental to live coral by boring into it, this activity also contributes to the natural bioerosion process, which is essential for the balance of calcium carbonate in reef ecosystems.

Habitat

This sponge species is found in tropical and subtropical waters, often in association with coral reefs. It can be found at various depths, typically where there is an abundance of sunlight to support the photosynthetic organisms that many sponges harbor symbiotically within their tissues.
