General Description
The Spiny Sea Cucumber, scientifically known as Pentacta anceps, is a vibrant marine species found in home reef aquariums. Boasting a striking color palette of green with pink and yellow hues, this sea cucumber showcases rows of pink knobby thorns running along its body. With eye-catching yellow and pink tentacles that extend during feeding, it is a visually appealing addition to aquariums.
Aquarium Suitability
Considered suitable for expert aquarists, the Spiny Sea Cucumber thrives in reef aquariums with a capacity of over 30 gallons. Due to its filter-feeding nature, a diligent care routine is essential to support its unique requirements.
Demands, Care, and Hardiness
Requiring careful attention, this sea cucumber must be housed in a stable environment with proper water flow. To maintain optimal health, daily feeding with zooplankton or liquid invertebrate food is recommended. Ensuring that nitrate levels remain low and avoiding copper-based medications are crucial for its well-being. Acclimation procedures should be meticulous to prevent stress-related issues.
Reef Suitability
Rated as reef-compatible, the Spiny Sea Cucumber can peacefully coexist in reef tank setups. Its filter-feeding habit contributes positively to the overall ecosystem within a reef aquarium.
Aquarium Setup
Creating a suitable habitat for the Spiny Sea Cucumber involves providing adequate water conditions such as a pH range of 8.1 to 8.4, a specific gravity of 1.023 to 1.025, and a carbonate hardness (KH) level between 8-12. A minimum tank size of 113 liters is advised to accommodate this species comfortably.
Behaviour
Known for its peaceful temperament, the Spiny Sea Cucumber typically remains stationary once it finds a suitable spot in the aquarium. Its behavior of filtering small particulates from the water column contributes to the cleanliness of the tank.
Feeding and Diet
As a filter feeder, the Spiny Sea Cucumber utilizes its hair-like appendages to capture small particles from the water, which are then transferred to its mouth for consumption. Regular feeding with zooplankton or liquid invertebrate food is necessary to meet its nutritional needs.
Habitat and Distribution
In the wild, Pentacta anceps is found in marine habitats with suitable conditions for filter feeding. Their distribution spans specific regions where they can thrive, contributing to the ecological balance of their respective ecosystems.
