Description
The Gold & Blue Maxima Giant Clam is a striking Tridacna maxima displaying a golden-brown to bronze mantle covered with dense electric-blue and turquoise spots. Under blue reef lighting, the blue fluorescence becomes especially prominent, creating a beautiful contrast against the warm metallic base coloration. The clam is attached to the rockwork and extends its mantle beyond the shell to maximize light exposure.
Lighting
Moderate to high lighting
PAR: 150–350
Placement (Aquarium Zone)
Middle to upper reef
Prefers a stable rock or solid substrate where it can securely attach its byssal foot. Provide adequate space around the mantle for full expansion.
Temperature
24–27°C (75–81°F)
Salinity
1.024–1.026 SG
pH
8.1–8.4
Alkalinity
8–10 dKH
Calcium
420–450 ppm
Magnesium
1280–1380 ppm
Flow
Moderate, indirect flow
Avoid strong direct flow that causes the mantle to remain retracted.
Diet
Primarily Photosynthetic
Supplemental foods:
Phytoplankton
Fine particulate coral foods
Marine microplankton
Reef plankton preparations
Healthy established clams obtain most of their nutrition from their symbiotic zooxanthellae.
Adult Size (up to)
Approximately 30–40 cm (12–16 inches)
Care Level
Intermediate to Advanced
