根须石珊瑚（Rhizotrochus typus）

关于根须石珊瑚（Rhizotrochus typus）

Rhizotrochus is a solitary, non-photosynthetic stony coral that anchors itself with root-like projections and feeds via long tentacles. It needs no strong lighting but demands careful feeding, making it best suited to experienced reef keepers.

迎接根须石珊瑚（Rhizotrochus typus）前需要了解的7件事

1. 1Feeding Is Essential

   Since it lacks zooxanthellae, it can't rely on photosynthesis for nutrition. Its survival and growth depend on regular feeding, so food such as zooplankton needs to be delivered within reach of its tentacles.

2. 2A Solitary Coral

   Rhizotrochus has just one corallite and doesn't form colonies. Each individual exists as its own distinct organism rather than part of a larger structure.

3. 3Root-Like Anchoring Structures

   It extends root-like projections from the base of its corallite to anchor itself to rock or sand. This distinctive structure is actually the source of the genus name.

4. 4Long, Translucent Tentacles

   At feeding time, it extends long, translucent tentacles to capture food drifting in the water. Whether the tentacles are extended or retracted depends on the timing of your observation.

5. 5No Strong Lighting Needed

   Because it lacks zooxanthellae, it doesn't require the intense lighting setups other corals need. Instead, nutrition management centers on feeding rather than light.

6. 6Prefers Gentle Water Flow

   Since it relies on extending its tentacles to catch food, it tends to do better in gentler flow rather than areas hit by strong, constant current. Placement should be adjusted based on the flow pattern within the tank.

7. 7Why It Suits Experienced Keepers

   Managing feeding frequency and timing calls for different knowledge than caring for photosynthetic corals. For this reason, it's considered a species best suited to keepers with prior coral-keeping experience.

根须石珊瑚（Rhizotrochus typus）的常见问题

Q.Does Rhizotrochus need lighting to keep?

A.No, strong lighting isn't required since it lacks zooxanthellae. Instead, it needs regular feeding to make up for the nutrition it can't get from light.

Q.How often does it need to be fed?

A.This varies by individual and setup, but like other tentacle-feeding corals, regular feeding is essential. Food should be delivered within reach of its tentacles.

Q.Is this a good coral for beginners?

A.Rhizotrochus is considered a species for experienced keepers. Since it requires different care knowledge than photosynthetic corals, such as feeding management, it's best introduced after gaining some coral-keeping experience.

Q.Can it be kept in a tank with other corals?

A.Since it needs consideration for water flow and placement, check the flow pattern and layout of your tank when deciding where to position it.

Q.Is Rhizotrochus subject to CITES?

A.No, Rhizotrochus is not subject to CITES.
