About Duncan Coral

Duncan Coral is a hardy, beginner-friendly LPS coral known for its round, flower-like polyps and strong feeding response.

7 things to know before welcoming a Duncan Coral

1Provide Gentle, Indirect Flow
Duncan Coral needs some water movement to fully extend its polyps, but flow that hits it too directly or too strongly can keep them closed. Place it where gentle, indirect current reaches the colony.
2Moderate Lighting Is Enough
This coral doesn't require intense lighting, so it can be placed in a variety of spots in the tank, including the middle or lower areas. If you're unsure where to start, a moderately lit position is a safe first choice.
3Feeding Encourages Healthy Growth
Duncan Coral responds well to target feeding, and you can watch its polyps actively catch and consume food. Regular feeding tends to support good coloration and growth over time.
4Give It Space From Neighbors
As the colony grows, its skeleton branches out and new polyps form, gradually expanding in size. Leave enough space between it and neighboring corals when placing it in the tank.
5Avoid Sudden Water Changes
While relatively hardy, this coral—like most corals—is sensitive to abrupt shifts in water parameters. Keep temperature, salinity, and pH changes gradual, both during introduction and in ongoing care.
6Allow an Acclimation Period
It's common for the polyps to stay closed for a few days right after moving to a new tank. In most cases they relax and open again once the coral settles in, so give it time before worrying.
7A Long-Term Companion
Under proper care, Duncan Coral can live for over ten years, making it a companion you can enjoy in your tank for a long time. Getting into the habit of daily observation helps you stay on top of its condition.
