Common name: Fire Sponge

General information

The Fire Sponge, scientifically known as Tedania ignis, is a species of demosponge found in the warm waters of the Western Atlantic, including the Caribbean Sea and the Gulf of Mexico. It is known for its bright red to orange coloration and its rough, flame-like surface texture, which is where it gets its common name. This sponge is not recommended for beginner aquarists due to its potential to release toxins that can irritate human skin.

Care

Tedania ignis requires a well-established aquarium with stable water conditions and strong water flow to mimic its natural environment. It is a filter feeder, relying on the water current to bring it food particles. It does not require additional feeding, but the water quality must be high to provide sufficient nutrients. This sponge should not be exposed to air, as this can cause tissue damage.

Reproduction

Reproduction in Tedania ignis is both sexual and asexual. Sexual reproduction occurs through the release of gametes into the water column, while asexual reproduction happens through budding. In the aquarium, asexual reproduction is more common, allowing the sponge to spread across rock surfaces.

Symbiosis

While Tedania ignis does not have notable symbiotic relationships like those seen in clownfish and anemones, it does host a variety of microorganisms within its tissues. These microorganisms can include bacteria and single-celled algae, which may contribute to the sponge's nutrition and defense mechanisms.

Habitat

The Fire Sponge is typically found in shallow waters, often attached to hard substrates such as rocks and coral rubble. It thrives in areas with moderate to strong water flow, which facilitates its filter-feeding lifestyle. In the wild, it can be found at depths ranging from the intertidal zone to about 40 meters.
