Holothuria (Mertensiothuria) hilla is a species of sea cucumber prized for its role in maintaining substrate cleanliness in marine aquariums. Available in various sizes, this invertebrate is a beneficial addition to reef and fish-only systems alike.
Care Level: Easy to moderate. This species is hardy but requires stable water parameters and a well-established aquarium.
Diet: Detritivore. Feeds primarily on organic detritus and microalgae found within the substrate. Supplementary feeding with finely powdered marine invertebrate foods or specialised sea cucumber diets can be provided if natural food sources are insufficient.
Compatibility and Reef Safety: Generally reef safe with caution. Holothuria hilla is peaceful and coexists well with most reef inhabitants. However, ensure it is not housed with aggressive predators that may harm it.
Tank Requirements: A minimum tank size of 75 litres (approximately 20 gallons) is recommended to provide adequate substrate area for foraging. Moderate water flow is preferred to maintain water quality without disturbing the substrate excessively.
Placement: Place on sandy or fine rubble substrate where it can burrow and feed naturally. Avoid placing near strong currents or areas with heavy sediment disturbance.
Lighting: Standard aquarium lighting is sufficient as this species does not rely on photosynthesis.
Origin: Not Provided.
Maximum Size: Typically grows up to 15 cm in length.
Holothuria (Mertensiothuria) hilla is an excellent choice for hobbyists looking to enhance the biological filtration and substrate health of their marine tanks. Regular monitoring of water parameters and gentle handling during maintenance will ensure its wellbeing.
