Derasa Clam: A Stunning and Hardy Giant for Your Reef

Add the magnificent Derasa Clam to your marine aquarium! Known for its striking colors and relatively robust nature, it’s an exceptional centerpiece for vibrant reef environments.

Overview

The Derasa Clam (*Tridacna derasa*) is celebrated for its impressive size and captivating beauty. Its thick, smooth shell features distinctive vertical folds, and its fleshy mantle displays intricate patterns of gold, brown, and yellow, often rimmed with brilliant electric blue or green. A peaceful, photosynthetic bivalve, it anchors securely to your sand bed, contributing to your tank’s natural filtration.

Care Level

Considered one of the hardiest giant clam species, the Derasa Clam is suitable for intermediate aquarists committed to stable reef conditions. It’s peaceful and reef-safe, making it an excellent addition to diverse marine setups, though watch for fish known to nip at mantles.

Tank Essentials

A mature reef aquarium of at least 200 litres is recommended for smaller specimens, with 380+ litres ideal for full growth. Provide moderate to intense lighting (high PAR) and stable water parameters: pH 8.1-8.4, temperature 22-26°C, and specific gravity 1.023-1.025. Ensure adequate calcium, alkalinity, and magnesium.

Diet

Primarily sustained by the symbiotic zooxanthellae in its mantle through photosynthesis, larger Derasa Clams typically require minimal supplemental feeding. Smaller clams (under 10 cm) should be offered phytoplankton a few times weekly.
