This sponge requires feedings of dissolved organic matter including marine snow and phytoplankton in order to maintain proper health.
Do not expose sponges to air. Air can become trapped in the matrix channels, which line the inside of its body blocking food from reaching its cells. This will result in the death of the sponge. When placing the sponge in the aquarium place the shipping bag in the aquarium and cut the bag open underwater. Remove the sponge from the bag underwater and let it fall into the aquarium. Twist the shipping bag closed underwater, and discard the water in the bag. A small amount of shipping water will escape into your aquarium using this method
