Tropic Thunder Montipora – Large Frag

Montipora Tropic Thunder is a beautiful encrusting SPS (small polyp stony) coral known for its vibrant orange polyps and green base. Here’s a care guide to keep it thriving in your reef tank:

Tank Requirements

• Tank Size: Suitable for most tanks (nano to large) but best in stable, mature systems.

• Flow: Moderate to high. Strong but indirect flow helps prevent debris buildup and encourages healthy growth.

• Lighting: Medium to high (PAR 200-350). Too little light can dull its colors, while too much may bleach it.

• Placement: Mid to upper reef, depending on light intensity. Provide space for growth.

Water Parameters

• Temperature: 75-78°F (24-26°C)

• Salinity: 1.025 SG (35 PPT)

• pH: 8.1-8.4

• Alkalinity: 8-10 dKH

• Calcium: 400-450 ppm

• Magnesium: 1250-1350 ppm

• Nitrates: 2-10 ppm

• Phosphates: 0.02-0.05 ppm

Feeding & Growth

• Primary Nutrition: Photosynthesis via its symbiotic zooxanthellae.

• Supplemental Feeding: Occasional broadcast feeding with coral foods like Reef Roids, phytoplankton, or amino acids can promote faster growth.

• Growth Rate: Moderate to fast under optimal conditions.

Maintenance & Care

• Stable Water Conditions: SPS corals are sensitive to fluctuations, so keep parameters stable.

• Regular Water Changes: Helps maintain trace elements and water quality.

• Dosing: If heavily stocked with SPS, consider dosing calcium, alkalinity, and magnesium.

• Pest Prevention: Inspect for Montipora-eating nudibranchs, which can be a threat.
