Description
The Golden Blue-Lavender Giant Clam is a spectacular color morph displaying a rich golden-brown to olive shell with a vivid electric-blue and lavender mantle. Its mantle features intense turquoise-blue markings and fluorescent highlights that become especially striking under blue reef lighting. The combination of metallic gold, lavender, and electric blue gives this clam a highly exotic appearance, making it an impressive centerpiece for a mature reef aquarium.
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 sufficient space around the mantle for full expansion and avoid placing it where surrounding corals may shade it.
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 or prevents the clam from opening fully.
Diet
Primarily Photosynthetic
Supplemental foods:
Phytoplankton
Fine particulate coral foods
Marine microplankton
Reef plankton preparations
Healthy established giant clams obtain most of their nutrition from their symbiotic zooxanthellae.
Adult Size (up to)
Approximately 30–40 cm (12–16 inches), depending on species.
