Holothuria edulis

Caring for a “Burnt Sausage” Sea Cucumber (Holothuria edulis) requires a nuanced approach, as they are delicate creatures with specific needs. Here’s a consolidated care guide based on the information gathered:

Key Care Considerations:

• Tank Requirements:
  • Large Tank: They require a substantial tank with ample horizontal space for foraging. A minimum of 380 liters is recommended.
  • Sandy Substrate: A deep, fine sandy substrate is essential, as they sift through it for food.
  • Established Aquarium: They thrive in well-established aquariums with sufficient detritus. New aquariums may lack the necessary food sources.
  • Safe Equipment: Pumps and overflow boxes should be protected to prevent the sea cucumber from being sucked in, which could cause a toxic release.
• Water Parameters:
  • Stable Conditions: Maintain stable and high-quality marine aquarium water conditions.
  • Avoid Copper: They are sensitive to copper-based medications.
  • Avoid high levels of nitrates.
• Diet:
  • Detritivores: They primarily feed on detritus (decaying organic matter).
  • Supplementation: If detritus is insufficient, supplement with sinking algae wafers and occasional sinking shrimp pellets.
  • Some species of sea cucumber also require phytoplankton.
• Temperament and Compatibility:
  • Peaceful: They are peaceful creatures.
  • Tank Mates: Choose tank mates carefully. Avoid aggressive fish that may harass them.
  • Toxins: They can release toxins when stressed, which can harm other tank inhabitants.
  • It is often recommended to only keep one sea cucumber per tank.
• Important Precautions:
  • Toxicity Risk: Be aware of the risk of toxin release if the sea cucumber is stressed or injured.
  • Handling: Exercise caution when handling them.
  • Flow: Ensure that water flow is not excessive, as this can damage their feeding tentacles.
  • Overstocking: avoid overstocking your tank, as this can lead to the sea cucumber not having enough food.

In essence:

• Provide a stable, mature environment with plenty of sandy substrate.
• Ensure adequate food sources.
• Choose compatible tank mates and minimize stress.
