Yellow Freshwater Clam Corbicula Fluminea 4cm

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.
