Common name: Scalarispongia scalaris

General information

Scalarispongia scalaris, commonly known as the Scalar Sponge, is a species of marine sponge found in reef environments. This sponge is known for its unique and attractive growth form, which can add a natural and diverse element to a reef aquarium. It is characterized by its fan-like shape and often vibrant colors, which can range from purple to brown, depending on the specific environment and lighting conditions.

Care

The care of Scalarispongia scalaris in a reef aquarium requires stable water conditions and moderate to strong water flow to mimic its natural habitat. It is a filter feeder, relying on the water flow to bring it food in the form of microorganisms and organic particles. It is important to maintain good water quality with low levels of nitrates and phosphates to prevent algae overgrowth on the sponge's surface.

Reproduction

Sponges, including Scalarispongia scalaris, have a unique method of reproduction that can occur both sexually and asexually. In the aquarium, they often reproduce asexually through a process called budding, where a part of the sponge breaks off and grows into a new individual. Sexual reproduction involves the release of sperm into the water column, which then fertilizes eggs in other sponges, leading to the development of free-swimming larvae.

Habitat

Scalarispongia scalaris is typically found in tropical and subtropical reef environments. In the wild, they are often seen on reef slopes and overhangs where they can take advantage of the water flow for feeding. They can be found at various depths, often between the intertidal zone and deeper reef areas.
