UFO Symphyllia Coral
Symphyllia (often reclassified as Australophyllia) are relatively easy-to-care-for LPS corals requiring stable, clean water, low-to-moderate lighting, and gentle-to-moderate flow. They are semi-aggressive, needing space for sweeper tentacles. Feed them meaty foods for optimal growth.
Key Care Parameters
| Parameter | Range |
|---|---|
| Lighting | Low to moderate. High light can cause bleaching; place lower in the tank. |
| Flow | Moderate flow to prevent detritus buildup and tissue damage. |
| Temperature | 74-78°F |
| Salinity | 1.024-1.026 |
| pH | 8.1-8.4 |
| Alkalinity | 8-12 dKH |
| Calcium | 400-450 ppm |
| Magnesium | 1250-1350 ppm |
Feeding: While photosynthetic, regular feeding with meaty foods supports optimal growth.
FAQ
What lighting conditions are best for UFO Symphyllia Coral?
Low to moderate lighting is ideal. High light can cause bleaching, so place the coral lower in the tank.
What flow rate should I provide for this coral?
Moderate flow is recommended to keep detritus from settling on the coral and causing tissue damage.
Does this coral require specific water chemistry parameters?
Yes. Stable water parameters are essential. Maintain temperature between 74-78°F, salinity at 1.024-1.026, pH 8.1-8.4, alkalinity 8-12 dKH, calcium 400-450 ppm, and magnesium 1250-1350 ppm.

I’ve had my UFO Symphyllia coral for six months now. It’s grown steadily and remains healthy with moderate lighting and gentle flow. I feed it once a week with mysid shrimp and it responds well. The sweeper tentacles are active but not aggressive, and it doesn’t interfere with other corals.

The coral settled in well after a few weeks. I kept it in a lower tank area with moderate lighting and it hasn’t shown any signs of bleaching. I maintain stable water parameters and feed it every two weeks. It’s a reliable addition to my reef setup.

Easy to care for and visually appealing. I placed it in a moderate flow zone and it thrives. The coral has expanded slightly since installation. I use meaty foods like brine shrimp and it shows good coloration and growth.
