Datasheet

General Description

The Maxima Clam, also known as the Small Giant Clam, is a popular species of giant clams characterized by its vibrant mantle patterns and colors. In the wild, they can grow up to 12 inches and are commonly found in the Central and South Pacific. Maxima Clams are cultivated in clam farms and exhibit a range of colors and patterns, graded based on size and color intensity.

Aquarium Suitability

Maxima Clams are suitable for reef aquariums with intense lighting due to their symbiotic relationship with zooxanthellae algae. They are filter feeders and do not require supplemental feedings if larger than 2 inches. Smaller clams under 2 inches may need phytoplankton supplements a few times a week.

Demands, Care, and Hardiness

These clams require intense lighting, stable water chemistry with calcium levels between 380-450 mg/L, alkalinity between 8-11 dKH, and magnesium levels of 1280-1350 ppm. Good water flow is essential for their well-being, and they are relatively hardy when provided with suitable conditions.

Reef Suitability

Maxima Clams are well-suited for reef aquariums, where they can add beauty and diversity. They attach to hard substrates using byssal filaments and require a stable environment with appropriate lighting and water parameters for optimal health.

Aquarium Setup

For aquarium setup, provide intense lighting for photosynthesis and ensure proper water flow. Acclimate smaller clams to intense lighting gradually. Maintaining calcium, alkalinity, and magnesium levels within the recommended range is crucial for their well-being.

Behaviour

Maxima Clams can attach themselves firmly to solid surfaces within the aquarium using byssal threads. Care should be taken not to damage these threads when moving or relocating the clams.

Feeding and Diet

Maxima Clams are primarily photosynthetic, deriving nutrition from zooxanthellae. Larger specimens do not require supplementary feedings, but smaller clams may benefit from phytoplankton supplements several times a week.

Habitat and Distribution

In the wild, Maxima Clams are found in the Central and South Pacific regions, often forming congregations. They attach to hard substrates and may bore into porous materials over time for anchorage. Cultivated clams are available in a variety of colors and patterns, adding to their appeal in aquarium settings.
