Описание
Tridacna maxima is a popular, highly sought-after, and challenging (intermediate-level) reef aquarium clam known for its intense, varied mantle colors (blue, green, gold, purple) and intricate patterns. They require high-intensity lighting, stable water parameters (calcium 400-440 ppm), and a rocky substrate for attachment. Maximas are smaller, growing up to 12-16 inches, and prefer to be placed high in the tank with moderate to high water flow.
Key Characteristics & Requirements:
-
Appearance: Features highly variable, vibrant mantles with spots, stripes, or mottled patterns. Their shells are less symmetrical than other clams, with small scutes.
-
Size: Generally grows to around 12 inches (30 cm) in aquariums, though some may grow slightly larger.
-
Lighting: Requires intense lighting (Metal Halide or high-output LED).
-
Placement: Must be placed on a hard, rocky surface where they will attach using byssal threads.
-
Flow: Prefers moderate to high, chaotic water movement rather than simple, laminar flow.
-
Diet: Primarily photosynthetic (symbiotic algae), but smaller specimens (inches) benefit from frequent phytoplankton feedings.
-
Placement Strategy: Ideal for placing in rocky, high-light areas of the reef scape.
Aquarium Compatibility & Care:
-
Difficulty: Intermediate.
-
Temperament: Peaceful.
-
Reef Safe: Yes.
-
Tank Size: 75-100+ gallons.
-
Acclimation: Requires slow acclimation to lighting to avoid bleaching.
-
Potential Hazards: Beware of parasites like pyramidellid snails and fish that may pick at the mantle (e.g., angelfish, wrasses).
