Common name: Blue Sponge

General information

The Blue Sponge, scientifically known as Haliclona viscosa, is a captivating marine sponge species that adds a touch of vibrant blue to the reef aquarium. This sponge is not only admired for its aesthetic appeal but also for its role in the natural filtration of the aquarium ecosystem, as it feeds on dissolved organic matter and bacteria.

Care

Caring for Haliclona viscosa requires a stable aquarium environment with moderate to strong water flow and good water quality to mimic its natural habitat. It is important to ensure that this sponge is never exposed to air, as trapped air bubbles can be fatal. The Blue Sponge thrives in indirect lighting conditions and benefits from the addition of trace elements and iodine to support its growth and health.

Reproduction

In the wild, Haliclona viscosa reproduces both sexually and asexually. In the aquarium, asexual reproduction through budding or fragmentation is more common, allowing hobbyists to propagate the sponge by carefully cutting a piece of it and attaching it to a rock or another surface in the tank.

Habitat

Haliclona viscosa is typically found in shallow waters of the Atlantic Ocean, from the North Sea to the Mediterranean. It prefers rocky substrates and often grows in areas with strong currents, which provide a continuous supply of food particles.
