Overview
The pearl gourami (Trichopodus leerii) is the elegant, grown-up gourami — a graceful, lace-and-pearl patterned fish that a male in breeding dress makes one of the most beautiful in the hobby.
Crucially it is very hardy, adaptable and long-lived (8+ years), with none of the disease and aggression baggage of the dwarf gourami — a superb centrepiece for anyone with the space.
Water & tank
Remarkably adaptable on chemistry (pH 5.5–8.0, 2–30 dGH) at 25–28 °C / 77–82 °F. Like all gouramis it breathes surface air, so keep a lid with an air gap; give it a calm, planted tank with surface cover.
It grows to ~12 cm, so give it room — at least ~75 L / 20 US gal (SeriouslyFish recommends a 90 × 30 cm base).
Feeding
An omnivore — a quality flake/pellet base plus small live/frozen foods. It will even hunt down hydra and other small pests. Feed small amounts once or twice a day.
Behaviour & tankmates
Peaceful and graceful — excellent in a calm community with other medium, non-aggressive fish. Its long pelvic "feelers" can be nipped, so avoid fin-nippers.
Can be kept singly, as a pair, or a small group given enough space.
What to expect
A settled pearl gourami glides serenely through the mid-water; a male colours up with a fiery orange breast when comfortable and in breeding condition — a sign of a happy, stable tank.
Myths, kindly busted
“All gouramis are aggressive or disease-prone like dwarf gouramis.”
The pearl gourami is peaceful, hardy, adaptable and long-lived — one of the most trouble-free centrepiece fish, given space.
“Gouramis don't need a lid.”
They breathe air at the surface, so they need a lid with an air gap above the water — and they can jump.
When to act
We triage, not diagnose — but these are worth a closer look (starting with a water test):
- Clamped fins, hiding or colour loss — test the water first; pearls are hardy, so a decline usually means a water or tankmate problem.
- Nipped, ragged pelvic feelers — check for fin-nipping tankmates.
