Pearl Gourami Care Guide - Aquarium Setup, Diet & Breeding

The Pearl Gourami is named for the pattern of pale, pearl-like spots that covers its warm brown or silvery body. A dark horizontal stripe runs from the eye towards the tail, while the throat and breast often develop a rich orange-red colour, especially in mature males. Long, thread-like pelvic fins are used as sensitive tactile organs as the fish explores its surroundings.

This is a peaceful, graceful gourami with a calm swimming style and an inquisitive personality. Pearl Gouramis can breathe atmospheric air using their labyrinth organ, allowing them to make use of oxygen-poor waters in the wild. They regularly rise to the surface, where they take gulps of air.

In nature, they are associated with shallow, slow-flowing habitats filled with submerged roots, leaf litter and aquatic vegetation. Their mottled colouring and reflective spots help them blend into dappled, plant-filled surroundings while searching for small invertebrates and other edible organisms.

Pearl Gouramis are generally more sociable and less confrontational than many larger gourami species. Males may still display and defend small territories, particularly when breeding, but their elegant appearance and relatively gentle temperament make them a favourite for peaceful tropical community aquariums.

Pearl Gouramis are native to Southeast Asia, particularly Thailand, Malaysia, Sumatra and Borneo. They inhabit quiet, densely vegetated freshwater environments including forest streams, swamps, marshes and slow-moving waterways.

A pair of Pearl Gouramis should have an aquarium of at least 110 litres, with a footprint around 90 cm long; a larger tank is preferable for a group or a community arrangement. Use a gentle current, a secure lid and open access to the surface, since they breathe atmospheric air. Dense planting, floating plants, shaded areas, driftwood and smooth substrate replicate their quiet, overgrown habitat and provide visual barriers between fish. Leave some open swimming space and avoid turbulent filtration or consistently strong surface movement.

Pearl Gouramis reach a maximum of about 12 cm (4.7 inches). Males are usually slightly larger and more robust than females, while females commonly remain around 10 to 11 cm (3.9 to 4.3 inches).

Pearl Gouramis are omnivores that appreciate a varied diet. Offer a quality tropical flake or small pellet as the staple, supplemented with frozen or live foods such as bloodworm, daphnia, brine shrimp and mosquito larvae. Small amounts of soft vegetable matter or algae-based foods can also be included. Feed modest portions that are eaten quickly, as their small mouths are not suited to large foods.

Pearl Gouramis can live with peaceful community fish such as harlequin rasboras, peaceful tetras, danios, smaller barbs, kuhli loaches, corydoras and compatible peaceful catfish. They are best kept away from fin-nippers, boisterous species and aggressive or highly territorial fish, including tiger barbs, large cichlids and some other gouramis. Multiple males may quarrel in smaller aquariums, so provide plenty of cover and avoid overcrowding.

Pearl Gouramis are bubble-nest breeders. A male builds a nest among floating plants, displays to the female and embraces her beneath the nest as eggs are released and fertilised. The male gathers the eggs into the nest and guards them until they hatch, usually within 24 to 48 hours. Remove the female after spawning if the male becomes aggressive, and move the male once the fry are free-swimming. The tiny fry need infusoria or another suitably fine first food before progressing to newly hatched brine shrimp.

Mature males usually develop a stronger orange-red colour across the throat and breast, a more elongated dorsal fin and a pointed dorsal tip. Females are generally fuller-bodied, less intensely coloured and have a shorter, more rounded dorsal fin.
