Echinopora
Echinopora, also known as Ryumon coral, grows in plate-like to encrusting forms and sits in an interesting middle ground between LPS and SPS corals. Its polyps often reveal striking fluorescent greens and oranges, making it a real visual centerpiece in a reef tank. It's considered relatively hardy with a moderate growth rate, which makes it a practical choice as a foundation piece for aquascaping. Suited to intermediate keepers, Echinopora can thrive for 10 years or more under stable conditions, and mature colonies typically reach 10 to 40 cm across, so it's worth planning space accordingly.

About Echinopora
Echinopora (Ryumon coral) is a plate-to-encrusting species prized for its vivid green and orange fluorescence. Relatively hardy with moderate growth, it's a popular intermediate-level choice as an aquascaping base.
7 things to know before welcoming a Echinopora
1Growth Form
Echinopora grows as an encrusting mat that hugs the rock or as a flatter plate that spreads outward. Because it can eventually cover neighboring rockwork, it's worth planning extra space around it from the start.
2Color Under Lighting
The green and orange fluorescence comes from pigments in the coral's tissue, and how vivid it looks depends on your lighting spectrum. Adjusting placement and light angle is part of the fun of dialing in its best colors.
3Intermediate-Level Care
Sitting between LPS and SPS in its needs, Echinopora doesn't tolerate wild swings in water quality but stays fairly stable once parameters are under control. It's generally recommended for keepers who already have some coral-keeping experience with calcium and KH management.
4Planning for Growth
Mature colonies reach roughly 10 to 40 cm, so it's important to think beyond the size at purchase and leave room for future spread. Encrusting forms in particular expand outward, so give your layout some breathing room.
5Spacing from Other Corals
As it grows, contact with neighboring corals can trigger stinging responses such as sweeper tentacles, causing mutual damage. Leave adequate spacing when placing it, and rearrange early if a collision looks likely.
6Feeding Considerations
Most of its nutrition comes from photosynthesis via symbiotic algae, but occasional feeding of fine plankton-type foods can support color and growth. Feeding isn't essential, so prioritize good lighting and flow first.
7Thinking Long-Term
Under stable conditions, Echinopora can live for 10 years or more, so it helps to plan how you'll maintain the tank over that time. Getting water quality, lighting, and flow dialed in before bringing one home makes ongoing care much smoother.
Frequently asked questions about Echinopora
- Q.How difficult is Echinopora to keep?
- A.It's considered suitable for intermediate keepers. Since it sits between LPS and SPS in its care needs, it tends to stay fairly stable once you're comfortable with basic water quality management.
- Q.How large does Echinopora grow?
- A.Mature colonies typically reach about 10 to 40 cm. Since many grow in plate-like or encrusting forms that spread outward, it's best to place them with extra room to expand.
- Q.How long can Echinopora live in a reef tank?
- A.Under stable conditions, it can live for 10 years or more. Since it's a long-term commitment, it helps to have your water quality and lighting management set up well in advance.
- Q.Does Echinopora need to be fed?
- A.It gets most of its nutrition from photosynthesis through symbiotic algae, so feeding isn't required. Offering fine plankton-type foods occasionally can help support its color and growth.
- Q.Is Echinopora subject to CITES regulations?
- A.No, Echinopora is not subject to CITES.
