Tridacna squamosina is a visually captivating large clam species prized by marine aquarists for its unique shell morphology and vibrant mantle colours. At approximately 6cm, this clam is suitable for established reef tanks with stable water parameters.
Care Level: Moderate care is required to maintain optimal health. This species is sensitive to rapid changes in water chemistry and requires consistent conditions.
Feeding: Like other large clams, Tridacna squamosina relies primarily on photosynthesis via its symbiotic zooxanthellae algae. Supplementary feeding with phytoplankton or specialised clam foods can support growth, especially in lower light setups.
Lighting Requirements: Moderate to high lighting is recommended to support photosynthesis. LED or T5 lighting systems that provide full-spectrum light are ideal.
Water Flow: Gentle to moderate water flow is preferred to ensure nutrient exchange without causing mantle damage.
Placement: Position this clam on a stable, sandy or rubble substrate area where it can receive adequate light without risk of falling or being overshadowed by corals or rockwork.
Compatibility and Reef Safety: Tridacna squamosina is reef safe and compatible with most peaceful reef inhabitants. Avoid housing with aggressive fish or invertebrates that may nip at the mantle.
Tank Size: A minimum tank size of 120 litres (approximately 30 gallons) is recommended to provide sufficient space and stable water parameters.
Regular water testing and maintenance are essential to keep calcium, alkalinity, and magnesium levels within optimal ranges for shell growth.
