Description
The Maxima Giant Clam is a highly sought-after giant clam species prized for its vibrant mantle colors, intricate patterns, and intense fluorescence under blue reef lighting. It attaches securely to rockwork using its byssal foot and extends its mantle to maximize light exposure.
Lighting
Moderate to high lighting
PAR: 150–350
Placement (Aquarium Zone)
Middle to upper reef
Prefers stable rockwork 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)
30–40 cm (12–16 inches)
Care Level
Intermediate to Advanced
