Description
Pearl Gourami (Trichopodus leerii)
Overview
Trichopodus leerii, commonly known as the pearl gourami, is a striking freshwater labyrinth fish from the Osphronemidae family, native to slow-moving, vegetated waters of Southeast Asia, including Malaysia, Thailand, Borneo, and Sumatra. Named for its iridescent, pearl-like spots across a brownish body with a dark horizontal stripe, males display vibrant orange-red throats during breeding, while females are duller and silver-toned. Males grow to 10–12 cm, females slightly smaller. Their peaceful nature, air-breathing labyrinth organ, and elegant appearance make them ideal for community aquariums, though males can be territorial.
Care Requirements
Tank Size:
Minimum 110L for a pair; 210L or larger recommended for trios (1 male, 2 females) or community setups to reduce aggression.
Water Parameters:
- Temperature: 25–28°C) optimal 26–27°C for breeding.
- pH: 5.5–7.5 (slightly acidic to neutral).
- Hardness: 5–15 dGH (soft to moderately hard, TDS <200 ppm).
- Ammonia/Nitrite: 0 ppm.
- Nitrate: <40 ppm (ideally <20 ppm).
- Substrate: Fine gravel or sand; add leaf litter (e.g., Indian almond leaves) for tannins and natural aesthetics.
- Décor: Dense plants (e.g., Java fern, Amazon sword, Vallisneria) and floating plants for cover and bubble nest sites. Include driftwood or caves for hiding. Ensure surface access for air breathing.
- Filtration: Gentle to moderate flow using sponge or canister filters; avoid strong currents that disrupt bubble nests.
- Lighting: Low to moderate; floating plants diffuse light to reduce stress.
- Other: Secure lid recommended, as they may jump when stressed.
Maintenance
- Water Changes: 20–25% weekly with dechlorinated water to maintain stable parameters and low nitrates.
- Tank Cleaning: Siphon uneaten food and debris; lightly vacuum substrate to preserve beneficial bacteria.
- Testing: Weekly checks for pH, hardness, ammonia, nitrite, and nitrate using a reliable test kit.
- Equipment Check: Ensure filters provide gentle flow, heaters maintain stable temperatures, and surface access is unobstructed for air breathing.
Diet
- Type: Omnivorous with a preference for protein-rich foods; feeds on insects, larvae, and plant matter in the wild.
- Foods:
- Live/Frozen: Bloodworms, brine shrimp, daphnia, mosquito larvae (2–3 times weekly for vibrant colours).
- Dry: High-quality flakes or pellets (e.g., Hikari Tropical Pellets, Fluval Bug Bites).
- Occasional: Blanched vegetables (e.g., peas, spinach) or spirulina flakes for variety.
- Feeding: Small portions 2–3 times daily, consumed within 2–3 minutes to prevent overfeeding.
- Notes: Varied diet enhances pearl-like iridescence. They feed at surface and mid-water; ensure food is appropriately sized.
Behaviour and Compatibility
- Temperament: Peaceful but territorial, especially males during breeding. Females are less aggressive.
- Social Behaviour: Best kept as a pair (1 male, 1 female) or trio (1 male, 2 females) in larger tanks. Multiple males require >210 litres with ample hiding spots to minimize aggression.
- Compatible Tankmates:
- Small to medium peaceful fish: Neon tetras, harlequin rasboras, corydoras catfish, kuhli loaches.
- Bottom-dwellers: Otocinclus, bristlenose plecos.
- Incompatible: Aggressive or fin-nipping fish (e.g., tiger barbs, serpae tetras), large cichlids, or other gourami species (e.g., Trichopodus trichopterus) to avoid hybridization or territorial disputes.
- Notes: Dense vegetation and visual barriers reduce aggression. Monitor male interactions in community tanks.
Breeding Behaviour
Breeding Type: Bubble nest builders; males construct large floating nests among plants or debris using saliva bubbles.
