Digitata - German Blue Polyp

Digitata is a term used to refer to a group of corals belonging to the genus Montipora, specifically Montipora digitata. Montipora digitata is a species of stony coral found in the Indo-Pacific region. It is known for its branching growth form and intricate skeletal structure. Here's some information on the care of Montipora digitata corals:

1. Water Parameters:

   • Temperature: Montipora digitata thrives in temperatures ranging from 74°F to 82°F (23°C to 28°C).

   • Salinity: Maintain a stable salinity level between 1.023 and 1.025 specific gravity.

   • pH: Aim for a pH level of around 8.1 to 8.4.

   • Alkalinity and Calcium: Ensure appropriate levels of alkalinity (8-12 dKH) and calcium (380-450 ppm) to support coral growth and skeletal development.

   • Nitrate and Phosphate: Keep nitrate levels below 10 ppm and phosphate levels below 0.05 ppm to prevent excessive algae growth and promote coral health.

2. Lighting:

   • Montipora digitata corals require moderate to high lighting. Provide them with a suitable spectrum of light, such as a combination of blue and white LEDs or T5 fluorescent bulbs.

   • Adjust the light intensity based on the coral's response. If the coral appears pale or growth is hindered, it may indicate insufficient lighting, and you should consider increasing the intensity.

3. Water Flow:

   • Moderate to high water flow is beneficial for Montipora digitata corals. It helps remove waste, provides oxygenation, and prevents debris from settling on the coral.

   • Ensure there is enough flow to prevent detritus buildup, but avoid placing the coral in a location with excessively strong, direct flow that could damage the delicate branches.

4. Feeding:

   • Montipora digitata corals are primarily photosynthetic and obtain much of their nutrition from symbiotic zooxanthellae. Adequate lighting is crucial for the zooxanthellae to thrive.

   • While they can capture some small food particles from the water, Montipora digitata corals have relatively low feeding requirements compared to other corals.

   • However, supplemental feeding with coral-specific planktonic foods can be beneficial, especially for faster growth and enhanced coloration. You can target feed them occasionally using a turkey baster or a pipette.

5. Placement:

   • Montipora digitata corals should be placed in an area with appropriate lighting and water flow.

   • Leave sufficient space around the coral to allow for growth and expansion of its branches without interfering with neighboring corals.

6. Regular Maintenance:

   • Regularly monitor water parameters using reliable test kits and maintain stable conditions.

   • Perform routine water changes to replenish trace elements and maintain water quality.

   • Keep an eye out for any signs of stress, such as tissue recession, pale coloration, or excessive mucus production, and take appropriate action if needed.

It's important to note that individual corals within the Montipora digitata species can vary in their specific care requirements and sensitivity. Observing the coral's response and making adjustments accordingly will help ensure its health and vitality in your aquarium.
