Common name: Phorbas tenacior
General information
Phorbas tenacior, commonly known as the Red Encrusting Sponge, is a marine sponge species that adds a vibrant touch of color to the reef aquarium. This sponge is known for its bright red to orange coloration and its encrusting growth form, which can cover rocks and other surfaces in the tank. It is a filter feeder, drawing in water to extract nutrients, and is an excellent indicator of good water quality in the aquarium.

Care
The Red Encrusting Sponge requires a well-established aquarium with stable water conditions. It thrives in moderate to high flow areas that facilitate its filter-feeding habits. Lighting should be moderate, as high-intensity lighting can promote the growth of algae over the sponge's surface, which can be detrimental. It is important to note that sponges should never be exposed to air, as trapped air bubbles can cause tissue damage and lead to the sponge's death.
Reproduction
In the aquarium, Phorbas tenacior can reproduce asexually through budding, where parts of the sponge break off and attach to another surface to grow. Sexual reproduction is less common in captivity but involves the release of gametes into the water column.
Habitat
Phorbas tenacior is typically found in the Mediterranean Sea and adjacent Atlantic areas. It prefers rocky substrates and is often found at depths where light is present but not too intense, allowing for the coexistence with other light-dependent organisms.
