Common name: Rhizotrochus Coral

General information

The Rhizotrochus typus, commonly known as Rhizotrochus Coral or Button Coral, is a solitary large polyp stony (LPS) coral that is highly prized in the reefkeeping hobby for its unique appearance and vibrant colors. It is characterized by its fleshy, round polyp which extends from a calcareous base. This species is not as common as other LPS corals in the trade, making it a sought-after specimen for advanced hobbyists.

Care

Rhizotrochus Coral requires moderate to high lighting conditions and moderate water flow within the aquarium to thrive. It is important to provide stable water parameters, as fluctuations can stress the coral and lead to poor health or loss of coloration. Feeding is also crucial for this species; target feeding with meaty foods such as mysis shrimp or finely chopped seafood can promote growth and vitality.

Symbiosis

While Rhizotrochus Coral does not have any well-known symbiotic relationships like those seen in clownfish and anemones, its structure can provide shelter for small, beneficial microfauna in the reef aquarium. These organisms can help maintain water quality and provide natural food sources for other inhabitants.

Habitat

Rhizotrochus typus is found in the Indo-Pacific region, typically in deeper waters on reef slopes where it can attach to hard substrates. In the wild, it is often found at depths where light is less intense, which is why it can adapt to a range of lighting conditions in captivity.
