Pachyseris Coral – Elephant Skin Coral
The Pachyseris Coral, also known as Corduroy Coral or Castle Coral, is a unique small polyp stony (SPS) coral that lacks visible polyps or tentacles. It develops distinct ridges and valleys that run parallel to its growing edge, giving it a texture resembling elephant skin.
This coral requires high light levels and should be placed in the mid-level or higher of the aquarium with strong water movement. Since it does not use polyps for feeding, consistent lighting is essential for proper nutrition. To maintain good health, regular supplementation of calcium, strontium, and other trace elements is necessary.

| Appearance: Ridges and valleys like elephant skin | High light level (mid-level or higher) |

The Pachyseris Coral looks stunning in my reef tank. The ridges are very pronounced and add a unique visual element. I’ve maintained high lighting and added calcium supplements as recommended. It’s thriving after a few months.

It’s a beautiful addition to my aquarium. The texture is exactly as described—like elephant skin. I keep it in the mid-level with good flow and have been feeding it with proper lighting and trace elements. Growth is steady.

I was initially skeptical about a coral without polyps, but it’s very stable and looks great. I follow the lighting and nutrient guidelines strictly. It’s one of the most visually interesting corals I’ve added.
