Common name: Tiger Tail Sea Cucumber
General information
The Tiger Tail Sea Cucumber, scientifically known as Holothuria difficilis, is a striking and beneficial addition to the reef aquarium. This species is known for its distinctive dark body with vibrant yellow to orange bands, resembling a tiger's tail. Sea cucumbers play a crucial role in the ecosystem by consuming detritus and organic matter, thus helping to maintain water quality and substrate cleanliness.

Care
Tiger Tail Sea Cucumbers require a well-established aquarium with a deep sand bed and plenty of live rock. They are sensitive to changes in water parameters, so stability is key. It's important to ensure that the aquarium does not have aggressive fish or invertebrates that might harm them. They are best suited for larger systems where they can roam without being trapped or injured by equipment.
Reproduction
In the wild, Holothuria difficilis reproduces by releasing eggs and sperm into the water column, a process known as broadcast spawning. In the aquarium, reproduction is rare, but if conditions are ideal, they may spawn, leading to the presence of tiny sea cucumber larvae.
Symbiosis
While not known for specific symbiotic relationships like clownfish and anemones, sea cucumbers do contribute to the overall health of the reef ecosystem. They provide a cleaning service by processing detritus and aerating the sand bed, which benefits other tank inhabitants.
Habitat
Tiger Tail Sea Cucumbers are found in the Indo-Pacific region, typically dwelling on the sea floor of reef environments. They prefer sandy substrates where they can burrow and sift through the sediment to find organic matter to feed on.
