Pearl Gourami

One of the calmest, most peaceful gouramis, with a pearly lace pattern. It grows larger than dwarf gouramis but is far milder — a great centrepiece for a big community.

• Minimum footprint: 30 gallons; a 40+ gallon tank gives real swimming room.
• Preferred swimming zone: top of the water column.
• Happy alone or as a compatible pair; avoid crowding with conspecifics.
• Care level: moderate.

• Temperature: 75–82°F
• pH: 6–7.5
• Hardness: 2–12 dGH (Moderate)

Stable parameters matter more than perfect ones — aim for consistency before chasing an exact number.

A further 1 species pair with Pearl Gourami as conditional — workable with the right tank and precautions.

Standard tanks at or above the recommended 40 gallons:

• 40 gallon Breeder 36 × 18 × 16″
• 40 gallon Long 48 × 12 × 16″
• 55 gallon 48 × 13 × 21″
• All tank sizes

• Start from a 30 gallon minimum and plan the full group size before you buy.
• Activity level is low, which affects how much of the tank it uses and how much it adds to the bioload.
• Zoning matters: this species lives mostly in the top zone, so choose tank mates that occupy other levels.

Compatibility depends on tank size, water chemistry, temperament, and adult size. Run a full check against any species in our database.
