To ensure the well-being of your Medusa Worm, provide a diet rich in detritus, algae, and small particles from the water column. These creatures are filter feeders, using their delicate tentacles to capture food particles from the water. A steady supply of tiny food particles will help sustain their health and vibrant appearance.

Tank Requirements and Aquascaping

Creating an optimal habitat for your Medusa Worm is vital for its well-being. Provide a spacious aquarium with a sandy substrate that allows it to burrow and move freely. A minimum tank size of 75 gallons is recommended to accommodate its size and movement. When designing your aquascape, consider incorporating live rock structures to provide hiding spots and create an environment that mimics its natural habitat.

Optimal Water Conditions for Medusa Worms

Creating and maintaining precise water conditions is crucial for the health and well-being of your Medusa Worms (Loimia medusa). Here's a more detailed breakdown of the optimal water parameters and conditions to ensure their thriving presence in your saltwater marine aquarium:

  • pH Level: Maintain a stable pH of 8.0 to 8.4. This pH range closely resembles the natural seawater environment and supports the overall health of your Medusa Worms.
  • Salinity: Keep the salinity of your aquarium water within the range of 1.024 to 1.026 specific gravity or approximately 32-35 ppt (parts per thousand). This closely mirrors the salinity levels of the ocean and provides a comfortable and stable environment for your Medusa worms.
  • Water Temperature: Maintain a water temperature between 74°F to 78°F (23°C to 26°C). This temperature range suits most marine aquarium inhabitants, including Medusa Worms, and promotes their metabolic processes and overall well-being.
  • Lighting Requirements: Medusa Worms are not particularly light-sensitive, and moderate to low lighting suits their needs. Avoid intense lighting, as it may stress them or promote excessive algal growth in your tank. A lighting schedule of 8 to 10 hours per day should be adequate.
  • Water Flow: Provide gentle water flow within your aquarium. Medusa Worms prefer a moderate water flow that helps disperse food particles and prevents sediment buildup. Powerheads or wavemakers can help you achieve the ideal water movement for your worms.
  • Water Quality: Maintain excellent water quality by regularly testing for ammonia, nitrite, and nitrate levels. Ammonia and nitrite should be undetectable, while nitrates should be kept at low levels, ideally below ten ppm (parts per million). Regular water changes, typically around 10-20% of the tank volume every two to four weeks, can help maintain water quality.
  • Filtration: Utilize a reliable and efficient protein skimmer to remove organic compounds and waste from the water. Proper filtration helps ensure water clarity and quality, reducing the risk of pollutants that may negatively affect your Medusa Worms.
  • Substrate and Aquascaping: Choose a fine, sandy substrate for your aquarium to allow the Medusa Worms to burrow and move freely. Incorporate live rock structures to provide hiding spots and create a complex environment that encourages their natural behaviors.
