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.
