Native range:

Habitat: Naturally found in large and dense aggregations on rock walls in nature, it tends to like vertical surfaces.

Maximum length: 5 cm (2 in)

Minimum aquarium size: 38 L (10 gal)

Lighting: Immaterial.

Water: Marine 24 °C (297 K, 75 °F) - 28 °C (301 K, 82 °F)

[edit] Feeding

Suspension feeder; needs lots of fine particulate foods. Phytoplankton supplementation or rotifers are necessary.

[edit] Aquarium Compatibility

Good aquarium animal. Hermit crabs, particularly the aggressive blue-legged hermits, need to be kept at minimum for this cucumber to survive. No reports of tank crashes or mortalities are linked to this species.

[edit] Special Care

Requires strong currents. Care should be taken to ensure the proper salinity and temperature.

[edit] Breeding/Propagation

Regularly asexually reproduces in captivity, dividing in two by splitting at about the midpoint of the body. The front half appears to grow a new rear end, and the converse occurs for the other half.
