Description

White Freshwater Clam (Corbicula fluminea)

Overview

The White Freshwater Clam is a small, attractive bivalve known for its pale cream-to-white shell and natural water-polishing abilities. As an efficient filter feeder, it helps remove fine particles from the water column, contributing to improved clarity in well-established aquariums. Best suited for mature tanks with stable conditions.

Origin

Native to East and Southeast Asia, commonly inhabiting rivers, streams, and lakes with sandy or fine gravel substrates.

Feeding

A dedicated filter feeder that consumes:

  • Suspended microalgae

  • Infusoria

  • Microorganisms

  • Fine organic detritus

In clean aquariums with low particulate matter, they may require supplemental phytoplankton or micron-sized liquid foods to prevent starvation.

Tank Mates

Peaceful and compatible with gentle community species such as:

  • Tetras & rasboras

  • Small gouramis

  • Corydoras

  • Shrimp

  • Snails

Avoid: Loaches, puffers, crayfish, large cichlids, or any species that may pick at or disturb burrowing bivalves.

Aggression

None. This clam is fully passive and will spend most of its time partially buried.

Experience Level

Intermediate. While hardy in stable conditions, they require:

  • Mature tanks with steady micro-food availability

  • Excellent water quality

  • Fine substrate for burrowing

Most losses occur from starvation in overly clean or newly established tanks.

Water Parameters

  • Temperature: 70–80°F (21–27°C)

  • pH: 6.8–8.0

  • Hardness: 6–18 dGH

  • Notes:

    • Very sensitive to ammonia and nitrite—must have pristine, established water.

    • Needs sand or fine gravel to burrow comfortably.

    • Should not be placed in tanks with strong currents.

The White Freshwater Clam (Corbicula fluminea) is a peaceful and beneficial filter feeder ideal for mature aquariums with stable conditions and gentle tank mates.
