Common name: Red Ball Sponge

Scientific name: Aaptos suberitoides (Brøndsted, 1934)

General Information

The Red Ball Sponge, scientifically known as Aaptos suberitoides, is an intriguing addition to marine aquariums. Renowned for its striking red coloration and spherical shape, this sponge adds a unique aesthetic to any reef setup. Like many other marine organisms, sponges like Aaptos suberitoides are filter feeders, playing a crucial role in maintaining water quality by filtering out particulates and organic matter.

This species is relatively new to the aquarium trade but has quickly gained popularity among hobbyists for its vibrant color and ease of care. Sponges are fascinating organisms that lack a nervous, digestive, or circulatory system, relying on the constant flow of water through their porous bodies to obtain nutrients and oxygen.

Care

The Red Ball Sponge is considered easy to care for, making it suitable for both novice and experienced aquarists. It thrives in well-established reef tanks with stable water parameters. Ensure that the sponge is placed in an area with moderate to strong water flow to facilitate its filter-feeding process. Avoid placing the sponge in direct light, as excessive light can cause algae to grow on its surface, potentially harming it.

To enhance the sponge's health, maintain high water quality with regular water changes and avoid the use of chemical treatments that could harm the sponge. Sponges are sensitive to air exposure, so handle them with care and avoid removing them from the water.

Diet and Feeding

Aaptos suberitoides is a filter feeder, relying on the constant flow of water through its body to capture plankton and other microscopic organisms. In a well-established reef tank, the sponge will typically find enough food on its own. However, supplemental feeding with phytoplankton or commercially available liquid foods designed for filter feeders can support its nutritional needs.

Feed the sponge by adding liquid food to the tank water, ensuring it is well-dispersed to reach the sponge. Avoid overfeeding, as excess nutrients can degrade water quality and harm other tank inhabitants.

Behavior and Compatibility

The Red Ball Sponge is a peaceful and non-aggressive species, making it an excellent addition to community reef tanks. It does not pose any threat to fish, corals, or other invertebrates. However, be mindful of tank mates that may nip at or disturb the sponge, such as certain species of angelfish or butterflyfish.

Health and Common Issues

In captivity, the Red Ball Sponge can thrive for many years with proper care. Ensure stable water conditions, regular feeding, and avoid exposing the sponge to air or direct light. When selecting a sponge, look for vibrant coloration and a firm, intact structure. Avoid specimens that appear discolored, have visible damage, or emit a foul odor.

Common issues include algae overgrowth and tissue necrosis, often caused by poor water quality or inadequate water flow. Address these issues promptly by improving tank conditions and ensuring the sponge receives adequate water movement.

Habitat

Aaptos suberitoides is naturally found in the Indo-Pacific region, often inhabiting coral reefs and rocky substrates. It prefers shaded areas with moderate to strong water flow, which supports its filter-feeding lifestyle. Replicating these conditions in a home aquarium will help ensure the sponge's health and longevity.
