Description de l'espèce
Geographical Origin and Habitat: A freshwater species; the enclosure should provide stability, oxygenation, space and shelter consistent with its behaviour without turning one habitat description into a mandatory recipe.
Taxonomy and Morphology: The accepted scientific name is Trichopodus leerii; the verified classification records genus Trichopodus, family Osphronemidae, subfamily Trichogastrinae, order Anabantiformes. Historical names remain searchable as synonyms rather than separate species.
Social Behavior: Pearl Gourami can be kept alone or in a compatible pair or group. The minimum reference is one individual; sex, maturity and available space can require a more conservative composition. Observe access to food, resting behaviour, chasing and use of shelter. Isolation, persistent competition or aggression means the number, composition or environment needs to be corrected.
Coloration and Sexual Dimorphism: Colour and shape can vary with age, sex, physiological state and environmental conditions. Identification and sexing require recognized species-level characters; one appearance or photograph is not enough.
Soins, reproduction et cohabitation
Aquarium Setup: Pearl Gourami needs an aquarium of at least 120 litres, sized for adult body size and a minimum group of one individual. Filtration, shelter and swimming room must match the species and the actual number kept. Volume alone does not make an enclosure suitable: tank shape and length, usable area, oxygenation and the ability to separate territories must reflect adult behaviour.
Diet and Feeding: The recorded diet is omnivorous. Offer appropriately sized foods varied within that category, and adjust quantity and frequency from actual intake, body condition and leftovers. One food or a fixed schedule is not suitable for every age and situation.
Water Quality: Maintain stable, well-oxygenated water appropriate to a freshwater species; the card's reference values are 24–28 °C, pH 5.5–7.5. Verify conditions with reliable tests and size maintenance and filtration to the actual load. Ranges are not automatic thresholds for treatment or rapid chemical correction.
Compatibility and Cohabitation: The cohabitation profile is suitable for a compatible community, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
Aquarium Breeding: The recorded reproductive profile is “oviparity”. Breeding should be attempted only with healthy adults, separation capacity and a plan for eggs or young. Do not treat unverified triggers, sex ratios or hatch times as universal for this species.
Risks and Diseases: Use a secure cover and close escape gaps. Prevent problems through quarantine of new arrivals, stable water, appropriate feeding and daily observation. Similar signs can have different causes, so check parameters, history and diagnosis before medication. Follow the product label and qualified aquatic-veterinary advice; there is no universal reduced dose for a species or family.

Profil de poisson
- Tempérament
- Peaceful
- Pearl Gourami has a generally peaceful temperament. Insufficient space, an unsuitable social ratio or incompatible tankmates can substantially change observed behaviour.
- Régime alimentaire
- Omnivore
- In the wild, The Pearl gourami is an opportunistic omnivore that consumes a wide variety of plant and animal matter. In captivity, they will readily accept high-quality flakes, pellets, and frozen foods like bloodworms and brine shrimp. Supplementing their diet with blanched vegetables or spirulina-based foods will ensure optimal health and coloration.
- Espérance de vie
- 4-8 years
- Taille adulte
- 12 cm
- Ratio des sexes
- Flexible
- Pearl Gourami can be kept alone or in a compatible pair or group. The reference minimum is one individual and must not be read as permission to overcrowd the aquarium.
- Fréquence d'alimentation
- Twice daily
- To maintain optimal digestion, The Pearl gourami should be fed small meals once or twice a day. It is important to only offer as much food as they can consume entirely within two to three minutes. Overfeeding can lead to severe water quality issues and potentially fatal digestive blockages.
- Charge biologique
- Medium
- The Pearl gourami generates a moderate bioload, requiring a balanced approach to aquarium filtration. Weekly water changes and regular vacuuming of the substrate are recommended to prevent the accumulation of dissolved organics. An appropriately sized canister filter or a well-designed internal filter is often highly beneficial.
- Courant
- Stagnant
- The Pearl gourami naturally inhabits slow-moving or stagnant waters, such as swamps, rice paddies, and densely vegetated ponds. They strongly prefer an aquarium with very gentle water circulation, as strong currents will cause them significant stress and exhaustion. Using a sponge filter or baffling the output of a power filter is highly recommended.
- Risque de saut
- Yes
- Like many fish, The Pearl gourami has the capacity to jump if startled by sudden noises, aggressive tank mates, or poor water parameters. While they are not notorious escape artists, they may leap during feeding time or breeding pursuits. It is always a wise precaution to maintain a tightly fitting lid to prevent any accidental escapes.
- Reproduction
- Oviparous
- During reproduction, the male of The Pearl gourami constructs a complex bubble nest at the water's surface, often incorporating floating plant material. After a delicate courtship embrace, the female releases eggs which the male meticulously collects and places into the nest. The male then fiercely guards the nest and fry until they are free-swimming, at which point he should be removed to prevent him from eating them.
- Compatibilité et compagnons
- Community
- The cohabitation profile is suitable for a compatible community, with a generally peaceful temperament. Keep at least one individual; tankmates, stocking density and decor must allow escape, rest and feeding without excessive competition. Watch interactions especially during feeding, maturity and breeding. Persistent chasing, injury or exclusion from food requires a change in stocking or layout, or separation of the animals.
- Niveau dans le bac
- Middle
- You will typically find The Pearl gourami swimming in the upper and middle regions of the aquarium. They occasionally venture to the bottom to forage but prefer the open swimming space and cover provided by tall plants in the upper layers. Providing a layout with plenty of vertical structure helps them feel most at home.
