Overview

WWC The Grinchy Porites is a vibrant SPS coral with an intense green base and contrasting red polyps. This coral’s encrusting growth pattern, combined with its ability to grow finger-like structures, gives it a unique texture and form-factor as it spreads across rockwork. Ideal for reef keepers with moderate experience, The Grinchy Porites offers both beauty and resilience, thriving in higher light and flow conditions typical of SPS environments.

Water Parameters

This coral thrives in stable water conditions with regular water changes. Corals with a hard skeleton, like this one, will consume calcium and alkalinity as they grow, often requiring additional supplementation. Routine water testing helps ensure these needs are consistently met.

• Specific Gravity (Salinity): 1.024-1.026
• Temperature: 75-78 Degrees F
• pH: 8.1-8.4
• Alkalinity: 8-9dKH
• Calcium: 380-450ppm
• Magnesium: 1300-1450ppm
• Nitrate (NO3): 10-30ppm
• Phosphate: 0.01-0.1ppm
• Nitrite (NO2): Undetectable
• Ammonia (NH3): Undetectable

Lighting Requirements

The Grinchy Porites does best in medium/high light, around 200-350 PAR. Although adaptable to other light conditions, gradual acclimation to these light levels is recommended to avoid stress. For those with mixed reef tanks, a PAR meter is invaluable for fine-tuning light levels across different corals, helping ensure each coral gets the right intensity for its needs. This careful setup supports the coral’s vibrant color and long-term health.

Ideal Tank Placement

Place Porites directly on rockwork where it will encrust onto the rock surface.

Water Flow Requirements

Strong water flow is ideal. The short polyps can withstand high flow that is typical of SPS reef tanks.

Aggressiveness and Compatibility

Like other encrusting corals, it's important to give The Grinchy Porites room to grow out.

Feeding and Nutrition

Primarily photosynthetic, this Porites can thrive on light alone, though occasional feedings with coral foods such as Reef Chili and Amino Acids like CoralAmino can enhance its growth and coloration.

Growth Rate and Pattern

This Porites has a moderate growth rate, spreading over the rock surface then growing finger-like structures upwards from the encrusting base.

Acclimation Process

Acclimation is essential for corals to adjust to their new environment. For a full step-by-step process, refer to our Coral Acclimation Guide.
