Common name: tiger tail sea cocumber

General information

The Tiger Tail Sea Cucumber, scientifically known as Holothuria thomasi, is a striking and beneficial addition to any reef aquarium. This species is known for its distinctive coloration, with a body that is generally black with vibrant yellow or orange bands, resembling a tiger's tail. They are part of the Holothuriidae family and play a crucial role in the ecosystem by consuming detritus and helping to maintain the cleanliness and balance of the substrate.

Care

Tiger Tail Sea Cucumbers are relatively easy to care for, provided that the aquarium has a sufficient amount of fine sand and detritus for them to sift through. They are sensitive to changes in water quality, so stable conditions and regular maintenance are essential. It's important to ensure that the tank has a secure lid, as sea cucumbers are known to climb and may accidentally leave the tank.

Reproduction

In the wild, Holothuria thomasi reproduces by releasing eggs and sperm into the water column, where fertilization occurs externally. In the aquarium, breeding is less common, but with optimal conditions, it is possible to observe spawning behavior.

Symbiosis

While Holothuria thomasi does not have any specific symbiotic relationships that are crucial for reefkeeping, their role as detritivores makes them symbiotic with the overall health of the aquarium ecosystem. They help to clean the substrate by consuming organic waste, which in turn benefits other inhabitants by reducing the potential for harmful nutrient buildups.

Habitat

Tiger Tail Sea Cucumbers are found in the tropical waters of the Indo-Pacific region. They typically inhabit reef slopes and lagoons, where they can be seen meandering across the sand bed, often partially buried.
