Common name: Branching tube sponge

General information

Aiolochroia crassa, commonly known as the Thick Sponge, is a species of sponge found in reef environments. This sponge is known for its robust and compact structure, often displaying a variety of colors such as beige, brown, or green. It has a unique texture and is a filter feeder, playing a crucial role in the nutrient cycle of reef ecosystems by processing organic matter suspended in the water.

Care

The care of Aiolochroia crassa in a reef aquarium requires stable water conditions with good water flow to mimic its natural habitat. It is essential to maintain high water quality, as sponges are sensitive to elevated levels of nitrates and phosphates. They thrive in areas with moderate to strong current, which facilitates their filter-feeding behavior. Supplemental feeding with plankton or other fine particulate organic foods can benefit their growth and health.

Reproduction

Aiolochroia crassa reproduces both sexually and asexually. Sexual reproduction occurs through the release of gametes into the water column, where fertilization takes place. Asexually, it can reproduce by budding, where a part of the sponge breaks off and develops into a new individual. In the aquarium, asexual reproduction is more commonly observed, allowing hobbyists to propagate the sponge by carefully cutting a piece and attaching it to a substrate.

Habitat

This sponge species is typically found in tropical and subtropical waters, often attached to hard substrates such as rocks or coral skeletons. It can be found at various depths, from shallow waters to deeper reef slopes, where it is exposed to a range of light conditions. In the aquarium, it should be placed in an area that receives moderate lighting and strong water flow to simulate its natural environment.
