Description
The Blue Maxima Giant Clam is a stunning Tridacna maxima prized for its intense blue to electric-blue mantle coloration and intricate fluorescent patterns. Under blue reef lighting, its vivid blue tones become especially prominent, creating a spectacular glowing appearance. Its mantle extends beyond the shell to maximize light exposure, making it an excellent centerpiece for a mature reef aquarium.
Lighting
Moderate to high lighting
PAR: 150–350
Placement (Aquarium Zone)
Middle to upper reef
Preferably placed on a stable rock or solid substrate where the clam can securely attach its byssal foot. Allow the mantle to expand without touching neighboring corals.
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 energy from their symbiotic zooxanthellae.
