Trichopodus leerii
The pearl gourami is one of the larger common Trichopodus species, named for the pearl-like spots along the body and the long, thread-like pelvic fins. It is generally peaceful and a favourite for spacious planted community tanks. Males develop a red throat when breeding and build bubble nests among floating plants. Shy if kept in bare tanks—provide structure, subdued lighting, and calm tankmates. Needs a long tank with surface area for labyrinth breathing and a secure lid.
Flake or pellets; frozen bloodworm or brine shrimp; vegetable matter; feed variety for long fins and colour.
Frequency: 1–2× daily
Do not overfeed; large surface area helps disperse feeding competition.
Native Region: Southeast Asia (Thailand, Malaysia, Indonesia—peat swamps and blackwater)
Slow, acidic, heavily vegetated waters; often stained with tannins.
Wide tank (120 L+), floating plants, driftwood, gentle filtration; avoid fast barbs or nippers.
Activity Level: Moderate
Graceful swimmer; may be shy; males territorial only during breeding in large tanks.
