Black Sea Cucumber

Holothuria sp.

Identification	A dark, sausage-shaped sand-sifting sea cucumber that slowly plows through the substrate ingesting sand.
Maximum Length	8″
Origin	Indo-Pacific
Minimum Tank Size	50 Gallon (mature sand bed)
Reef Compatibility	Reef safe. A beneficial detritivore that cleans and aerates the sand bed.

Behavior

A hardy, slow-moving deposit feeder that constantly processes sand, removing detritus, uneaten food and algae — an excellent natural sand cleaner. Needs a deep, established sand bed with enough surface area to feed.

Diet & Feeding

Detritus, diatoms and organic material sifted from the sand; supplemental feeding is rarely needed in a mature tank.

Cautions

Like all sea cucumbers, if it dies or is shredded by a pump it can release toxins that harm the tank — screen pump intakes and provide adequate sand area. Needs an established system.
