General Description
Sea cucumbers of the Holothuria genus are filter feeders that primarily sift through the substrate for food, with a notable preference for sandy substrates. These creatures, known for leaving behind distinctive "spaghetti-like" sand trails, range in size from 2 cm to a meter in length.
Aquarium Suitability
Sea cucumbers from the Holothuria genus are suitable for most aquarium setups but require a spacious tank with fine-grained sand, at least 2 cm in thickness, to support their feeding habits. They are known to release toxic chemicals when stressed or in distress, potentially harmful to tank inhabitants if proper precautions are not taken.
Demands, Care, and Hardiness
Considered hardy, these sea cucumbers are native to the East Indian Ocean and Indonesia. They are sensitive during transportation and acclimatization to new aquarium environments, emphasizing the need for care during these processes. Maintaining stable water conditions with pH levels between 8.1-8.4, a specific gravity of 1.020-1.025, and temperatures ranging from 22.2-25.6°C is crucial for their well-being.
Reef Suitability
Sea cucumbers of the Holothuria genus are always considered reef-safe, making them a compatible choice for reef aquariums without posing a threat to the coral or other reef inhabitants.
Aquarium Setup
To house these sea cucumbers successfully, a tank of at least 200 liters with a large area of fine-grained sand less than 2mm thick is recommended. Adequate filtration and circulation should be provided, ensuring that the sea cucumbers do not get stuck in pumps or overflow systems.
Behaviour
Holothuria sea cucumbers are peaceful in temperament and play a role in keeping the sand clean within the aquarium. They may shrink if not provided with enough food, underscoring the importance of a well-maintained environment.
Feeding and Diet
These sea cucumbers primarily feed on detritus and microalgae, such as spirulina. Ensuring a nutrient-rich environment with sufficient food availability is vital for their health and longevity.
Habitat and Distribution
Found predominantly in the East Indian Ocean and Indonesia, sea cucumbers of the Holothuria genus inhabit sandy substrates where they contribute to the ecosystem by filtering the sand for food.
