Notes: A colorful and bizarre addition to any reef aquarium, the Spiny Sea Cucumber can live for many years in the home aquarium. It will move around the aquarium until it finds an area with a good current where it can filter plenty of food. Once it finds a desirable spot it may stay there for many months.

The Spiny Sea Cucumber uses its oral tentacles to catch food that floats by. As each tentacle becomes full of food it draws its entire tentacle into its mouth. It must be fed foods for filter feeders including marine snow, phytoplankton, and zooplankton. If not properly fed the body of the Spiny Sea Cucumber will slowly begin to shrink.

The Spiny Sea Cucumber can be harmed by the intakes of any pumps or powerheads in the aquarium, so make sure to protect all intakes to prevent it from being sucked in.
