Black Cucumber Care Facts

Care Level: Expert
Temperament: Peaceful
Diet: Detritus
Reef Safe: Yes
Minimum Tank Size: 20 Gallons
Max Size: 10 inches
The Black Cucumber, Holothuria atra, also known as the Black Sea Cucumber, features a black/brown body that can grow up to 3-4 inches. They are reef safe but can emit poisonous toxins if attacked and injured. They will spend much of their time buried in sandy substrate - therefore a sandy bottom is essential. They will feed mostly on algae and detritus through sifting the sand. As they are easy to care for they make an excellent beginner cucumber species.

The Black Cucumber was received in great shape and has added life to my saltwater aquarium. Thanks
