Description

Yellow Freshwater Clam (Corbicula fluminea)
Overview
The Yellow Freshwater Clam is an attractive bivalve with a smooth, rounded shell that ranges from pale gold to rich yellow tones. Known for its natural water-filtering ability, it helps clear fine particles and improve water clarity in mature, stable aquariums. A peaceful, low-activity invertebrate best suited for experienced keepers who can provide a steady supply of microscopic food.
Origin
Native to East and Southeast Asia, inhabiting slow to moderately flowing rivers, lakes, and streams with sandy or fine gravel bottoms.
Feeding
A pure filter feeder that consumes:

Microalgae

Phytoplankton

Infusoria

Suspended organic particles

In very clean tanks, supplemental feeding with phytoplankton or fine liquid invertebrate foods is necessary to prevent starvation.
Tank Mates
Peaceful and best kept with gentle, non-predatory species:

Small tetras & rasboras

Peaceful gouramis

Corydoras

Shrimp

Snails

Avoid: Loaches, puffers, crayfish, crabs, and large cichlids that may harass or damage clams.
Aggression
None. This species is completely passive and spends most of its time partially buried in substrate.
Experience Level
Intermediate. Requires:

A mature aquarium with consistent micro-food

Very stable water conditions

Fine sand or gravel for burrowing

Excellent water quality

Most challenges come from insufficient food in newer or overly sterile tanks.
Water Parameters

Temperature: 70–80°F (21–27°C)

pH: 6.8–8.0

Hardness: 6–18 dGH

Notes:

Extremely sensitive to ammonia and nitrite—must have pristine water.

Provide soft to fine substrates for comfortable burrowing.

Avoid strong direct flow.

The Yellow Freshwater Clam (Corbicula fluminea) is a peaceful, attractive, and functional filter feeder that thrives in mature, stable aquariums with gentle tank mates and consistent microscopic food availability.
