Trichopodus leerii
The centrepiece gourami, fully grown males develop coppery throats, extended pelvic feelers, and pearl-spotted bodies. Genuinely peaceful when kept as 1 male + 2 females. Needs a tall tank for vertical territorial display and surface access for the labyrinth organ.
Pearl Gourami (Trichopodus leerii) reaches 10–12 cm as an adult and needs a minimum tank of 150 L. Native to Southeast Asia (Malay Peninsula, Sumatra, Borneo), it lives in the mid to top water column with a peaceful temperament. Aim for 24–28 °C, pH 5.5–7.5, and 2–15 dGH hardness. Lifespan is 4–8 years with good care. Keep pearl gourami in groups of 2+, pair or trio schoolers need numbers to display natural behaviour. Diet: omnivore, Flake, pellets, frozen bloodworms, mosquito larvae, blanched veg. Plant-safe: Yes. Shrimp-safe: Mostly (may eat very small shrimp).

Hard-won lessons from the tank.
The pelvic 'feelers' are sensory organs — males stroke courting females with them. In a tall planted tank with one male and two females, courtship displays are continuous and fascinating. Pearl gouramis live 5+ years in good care; one of the longer-lived commonly-sold tropical fish.
Genus 'Trichopodus' = 'hair foot' for the elongated pelvic 'feelers'. Species 'leerii' honours German aquarist Heinrich van der Leer.
What can go wrong and how to spot it.
Failure modes, in order of how dramatic the fix is.
Susceptible to bacterial infections in dirty water and the labyrinth-organ chilling that affects all gouramis from cold air. Always keep a lid; the air above the water needs to stay warm.
Mature pearl gouramis are spectacular but the juveniles in shop tanks look unimpressive — silver fish with vague spots. Buy them young and watch the transformation over 6–9 months as the spots sharpen and the male's throat colours up.
The practical routine, read top to bottom.
150 L+. Tall tank for vertical territorial display. Heavy planting along the back and edges with open mid-water swimming. Surface plants for security. Tannins from catappa leaves. Sponge or low-flow canister filter.
3 weeks. Provide cover.

Slow lowland swamps, ditches, and forest pools across the Malay Peninsula, Sumatra, and Borneo. Tannin-stained soft acidic water with dense surface and edge vegetation.
Insect larvae, small crustaceans, biofilm, occasional plant matter. Surface and mid-water feeders.
Habitat loss is a real concern across Southeast Asia. Most stock is captive-bred in Asian fish farms.
How they pair, reproduce, and grow.
Males have a coppery-orange throat (intensifying in breeding condition) and extended dorsal rays. Females stay silver-white with shorter dorsal fins. Both sexes show the pearl-spotted body pattern.
Bubble-nesters. Male builds a small nest under floating plants. Soft acidic water at 27–29 °C, very low flow. After spawning, male guards the nest aggressively — remove the female. Fry are tiny and need infusoria for the first week.
The named cultivars and the lookalikes worth flagging.
Wild type. Occasional 'mosaic gourami' (T. leerii) selectively bred for more uniform spotting. Avoid dyed variants.
Direct answers to the questions search engines and AI assistants surface most often about this species.
Pearl Gourami (Trichopodus leerii) needs a minimum tank of 150 L. They live in the mid to top water column and should be kept in groups of 2+, so a longer footprint matters more than depth.
Target 24–28 °C, pH 5.5–7.5, and 2–15 dGH hardness. Acclimate slowly when moving them between water sources.
Shrimp safety: Mostly (may eat very small shrimp). Plant safety: Yes.
Pearl Gourami are omnivore. Flake, pellets, frozen bloodworms, mosquito larvae, blanched veg.
On Fin & Stem's 1–5 difficulty scale this species rates 2/5. Forgiving, beginner-friendly once the tank is cycled. Breeding difficulty: medium (bubble-nester).
Typical lifespan in a well-maintained tank is 4–8 years.
A planted tank is a system. Pair this fish with one entry from each other pillar to plan the whole scape.
