It does well in a large aquarium if provided with ample room to roam. Generally, for every 3 inches of sea cucumber there should be 20 gallons of water. It prefers a thick sandy substrate so it can scour through the sand for organic foods. The Sea Cucumber will spend most of its time in the open, though it may carry a thin film of sand over its body. It needs to be kept with peaceful tank mates. It is sensitive to high levels of copper-based medications and will not tolerate high nitrate levels.
While it does not have the toxic tubules of Culvier that many cucumbers have, if frightened, it might disgorge its interal organs into the tank, which may be toxic to fish. In the wild, these organs often regenerate, but rarely in an aquarium setting.
