General Description
The Black Sea Cucumber, also known as the Black Sea Urchin or Lollyfish, is characterized by its long black body with occasional spots. This species was first identified in 1833 and is native to the Indo-Pacific region, spanning from the Red Sea to Hawaii. Typically, it inhabits sandy bottoms, often with a partial covering of sand.
Aquarium Suitability
The Black Sea Cucumber is considered suitable only for expert aquarists due to its specific care requirements and sensitivities. When kept in an aquarium, it should be housed with peaceful tank mates and not overstocked. A ratio of approximately 3 inches of the sea cucumber for every 20 gallons of water is recommended to maintain a suitable environment. Moreover, this species is highly sensitive to copper-based medications and high nitrate levels.
Care and Hardiness
This species requires meticulous care and is known to be sensitive to fluctuations in water quality. It is crucial to maintain stable water parameters within the optimal range. Additionally, the Black Sea Cucumber has a unique defense mechanism where it can expel its internal organs if threatened, though this phenomenon is rare in aquarium settings.
Reef Suitability
The Black Sea Cucumber is considered reef-compatible, making it a potential addition to reef aquariums. However, its placement within the tank must be carefully considered to prevent any accidental damage to corals or other reef inhabitants.
Aquarium Setup
When setting up an aquarium for the Black Sea Cucumber, it is ideal to provide a sandy substrate that mimics its natural habitat. Moderate water flow is recommended to ensure proper circulation. Maintaining stable water parameters, including a pH of 8.1-8.4, a specific gravity of 1.023-1.025, and a carbonate hardness (KH) of 8-12, is essential for its well-being.
Behaviour
Known for its peaceful temperament, the Black Sea Cucumber tends to coexist well with other tank inhabitants. It is generally a sedentary creature that contributes to the overall biodiversity of the aquarium ecosystem.
Feeding and Diet
As a filter feeder and omnivore, the Black Sea Cucumber primarily feeds on microorganisms and detritus present in the water column. Providing a nutrient-rich environment with ample sources of food is crucial for its nutritional requirements.
Habitat and Distribution
In its natural habitat, the Black Sea Cucumber is found in the sandy bottoms of the Indo-Pacific region, ranging from the Red Sea to Hawaii. It plays a vital role in the ecosystem by contributing to nutrient recycling and sediment turnover.
