WYSIWYG XMAS Goniopora
Goniopora corals, commonly called Flowerpot corals, are large-polyp stony (LPS) corals within the genus Goniopora. They are known for their beautiful, flower-like polyps that extend gracefully from a hard skeleton, creating a mesmerizing, waving motion in the current.
- Appearance: Each polyp resembles a daisy flower—long, slender tentacles with small “petals” at the tips.
- Colors: Found in vibrant shades of green, pink, red, purple, yellow, and even blue.
- Growth Form: Typically dome- or branching-shaped colonies.
- Natural Habitat: Shallow, turbid lagoons and reef flats across the Indo-Pacific region.
Care Requirements
Goniopora corals can be moderately challenging to keep, as they are sensitive to water quality and lighting. However, newer aquacultured varieties are more resilient.
1. Lighting
- Type: Moderate to strong lighting (PAR ~80–150).
- Sources: LED, T5, or metal halide lighting.
- Placement: Mid-level in the tank; avoid direct, intense light that can bleach the polyps.
2. Water Flow
- Flow: Moderate, indirect, and steady.
- Strong flow can cause polyps to retract or tear, while too little flow can lead to detritus buildup.
3. Water Parameters
| Parameter | Ideal Range |
|---|---|
| Temperature | 75–80°F (24–27°C) |
| Salinity | 1.024–1.026 SG |
| pH | 8.1–8.4 |
| Alkalinity | 8–9.5 dKH |
| Calcium | 400–450 ppm |
| Magnesium | 1250–1350 ppm |
| Nitrate | <10 ppm |
| Phosphate | <0.05 ppm |
Feeding
While Goniopora has photosynthetic zooxanthellae, it also benefits from direct feeding.
- Foods: Phytoplankton, zooplankton, rotifers, or specially formulated coral foods (like Reef Roids).
- Frequency: 2–3 times per week.
- Gently target feed with a turkey baster or coral feeder when polyps are fully extended.
Placement Tips
- Keep away from aggressive neighbors; tentacles can sting or be damaged by others.
- Avoid areas prone to sediment accumulation.
- Place in a stable environment where lighting and flow are consistent.
Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Polyps not extending | Too much light/flow or poor water quality | Adjust placement and check parameters |
| Tissue recession | Nutrient deficiency or bacterial infection | Maintain parameters, feed regularly |
| Algae growth | Excess nutrients or poor flow | Improve filtration, adjust lighting duration |
🌱 Propagation
- Propagation is delicate; typically done by careful fragging of healthy colonies using bone cutters and iodine dips to prevent infection.
