Lighting Requirements for Xenia Coral

Xenia coral thrives under moderate lighting. Popular reef lighting systems such as AI PRIME, RADION XR15, and KESSIL provide excellent results.

Too little light can slow pulsing and growth, while too much intensity may stress the coral.

Water Flow for Xenia Coral

Xenia prefers low to moderate flow. Too much flow can stop the pulsing behavior, while too little flow may allow debris to settle.

Flow equipment like Ecotech Vortech and Jebao wavemakers helps create proper movement.

Water Quality and Parameters

Xenia coral prefers stable but slightly nutrient-rich water compared to SPS corals.

• Temperature: 76–78°F
• Salinity: 1.025
• pH: 8.1–8.4
• Alkalinity: 8–10 dKH

Interestingly, Xenia often grows better in tanks that are not ultra-clean.

Placement in the Reef Tank

Xenia coral should be placed on isolated rocks or islands because it spreads quickly.

If left unchecked, it can overtake other corals in the tank.
