• Tank Size & Aquarium Setup

  • Minimum tank size: 60–80 liters (15–20 gallons)

  • Requires fine sand or soft substrate to anchor the tube base safely.

  • Avoid sharp rocks that can damage tentacles or puncture the base.

  • Recommended diet includes:

    • Phytoplankton and zooplankton

    • Finely chopped mysis shrimp or brine shrimp

    • Specialized invertebrate pellets

    • Occasional liquid or powdered coral foods

  • Feed 2–3 times weekly, ensuring particles reach tentacles.

  • Do not overfeed; uneaten food can pollute water and stress the anemone.

• Tank Mates & Compatibility

  • Reef-safe and compatible with peaceful fish and invertebrates.

  • Avoid aggressive or digging fish that may uproot the tube.

  • Safe with corals, snails, small shrimps, and gobies.

  • Can coexist with other sedentary invertebrates if ample space is provided.

  • Requires established, stable aquariums with clean water.

  • Minimal daily maintenance—mainly monitoring water parameters and feeding occasionally.

  • Gentle acclimation is recommended to prevent stress.

• Health & Special Notes

  • Sensitive to poor water quality or sudden changes in temperature and salinity.

  • Tentacles may retract when stressed but return to normal after acclimation.
