Green Pocillopora (Pocillopora spp.) – Description & Care
Green Pocillopora, also known as Green Pocillopora Coral, is a species of small-polyped stony (SPS) coral that is prized for its vibrant green coloration and unique, branching growth form. Pocillopora corals are characterized by their branching structures with fine, delicate branches, often forming a bushy or tree-like appearance. The green variation of Pocillopora can range from bright neon greens to more muted forest greens, which can vary in intensity depending on the lighting and water conditions. Green Pocillopora is a fast-growing coral and, like other Pocillopora species, it is known for being somewhat resilient, making it a popular choice for reef tank enthusiasts.
Care Requirements:
1. Lighting
- Moderate to Strong Lighting (PAR 200-300)
- Green Pocillopora thrives under moderate to strong lighting, which is necessary for optimal growth and coloration.
- LED, metal halide, and T5 lighting work well, with blue spectrum light bringing out the vibrant green hues.
- Too little light will result in poor growth and lack of vibrant coloration, while too much direct light can stress the coral, causing it to bleach or retract.
2. Flow
- Moderate to Strong Flow
- Pocillopora corals prefer moderate to strong water flow. This ensures that they receive proper nutrient exchange and helps prevent debris from accumulating on their delicate branches.
- Strong flow will help them extend their polyps more fully, but too much direct flow can cause physical damage or excessive polyp retraction.
- Ensure flow is evenly distributed around the coral without direct blasts of water.
3. Placement
- Mid to upper regions of the tank, where they can receive both strong lighting and moderate flow.
- Place them in a stable area of the tank with plenty of space to grow, as they can spread over time.
- Avoid placing them too close to other corals, particularly more aggressive species like Euphyllia or Acropora, as they can be stung by their sweeper tentacles.
4. Water Parameters
- Temperature: 74-78°F (23-26°C)
- Salinity: 1.023-1.025 SG (35 ppt)
- pH: 8.1-8.4
- Alkalinity: 8-12 dKH
- Calcium: 400-450 ppm
- Magnesium: 1250-1350 ppm
- Nitrates: 5-10 ppm
- Phosphates: 0.01-0.05 ppm
5. Feeding
- Photosynthetic coral, relying primarily on light for energy, but it will also benefit from occasional supplemental feeding.
- Target feed with zooplankton, mysis shrimp, or other coral foods like Reef Roids.
- While not strictly necessary, supplemental feeding can encourage faster growth and vibrant coloration.
6. Tank Mates & Compatibility
- Non-aggressive, Green Pocillopora can be placed with other SPS corals, as long as they are not too close to other aggressive species.
- It can also be kept with soft corals and LPS corals, though you should avoid putting it near larger stony corals that might sting it.
- Green Pocillopora does well with reef-safe fish, such as clownfish, wrasses, and tangs.
- Be mindful of any invasive species or aggressive corals, as Pocillopora corals can sometimes be overwhelmed in crowded tanks.
7. Special Considerations
- Fast-growing: Green Pocillopora is known for its rapid growth. In some cases, it may need to be fragged to prevent it from taking over space in the tank.
- Resilient: This species can adapt well to varying water conditions and moderate fluctuations in parameters, but stable conditions are always best.
- Fragging: Green Pocillopora can be easily fragged by cutting branches, but always use proper tools and handle with care to avoid stressing the coral.
- Acclimation: If introducing this coral to a new tank, make sure to acclimate it slowly to avoid stress from sudden changes in water parameters or lighting.
Green Pocillopora is a great option for aquarists looking for a beautiful, fast-growing SPS coral. With its vibrant green color and relatively easy care requirements, it’s an excellent addition to many reef tanks. While it grows quickly, its branching form allows for a natural, aesthetically pleasing display without overwhelming the tank.
