Pearl Gourami Care Guide (Trichopodus leerii): A Peaceful Centerpiece Fish
The Pearl Gourami (Trichopodus leerii) is widely considered one of the most beautiful and peaceful gouramis in the hobby. Its lacy, pearl-spotted body, delicate threadlike pelvic fins, and the warm orange-red throat that males develop when breeding make it a stunning centerpiece for a community tank. This pearl gourami care guide covers everything you need to keep them healthy. The accepted scientific name is Trichopodus leerii; you may also encounter the older name Trichogaster leerii in aquarium references.

The labyrinth organ
Like bettas and other gouramis, pearl gouramis are labyrinth fish: they have a special organ that lets them breathe air directly from the surface. This means they will periodically swim up to gulp air, and it is completely normal. Because of this, always leave a small gap of warm, humid air between the water surface and the lid, since chilled air can irritate the labyrinth organ.
Tank setup
Pearl gouramis appreciate a quiet, well-planted tank with gentle flow and some floating plants to diffuse light and provide cover. They can be a little shy, so plants and hiding spots help them settle in and show their best colors. Browse live aquarium plants, including floating varieties, to build their habitat. Subdued lighting from floating plants helps shy fish feel secure while leaving open access to the surface. Keep the water temperature steady around 77–82°F and stay consistent with maintenance using our water change guide.
Diet and feeding
These adaptable omnivores accept a wide range of foods. Use a quality flake or pellet as a staple and supplement with live or frozen foods such as bloodworms, brine shrimp, daphnia, and appropriately sourced mosquito larvae. Frozen foods should be thawed and portioned as directed; avoid collecting mosquito larvae from potentially contaminated water. They will also help pick at small pest organisms in the tank. Feed once or twice a day in modest amounts.
Behavior and temperament
Pearl gouramis are generally peaceful and among the calmer larger gouramis, which is a big part of their appeal. A male pearl gourami may become more territorial during breeding, so provide visual barriers and enough space for companions to retreat. Males may show mild territoriality toward each other, especially when breeding, so give them space or keep one male with several females. They generally coexist calmly with other peaceful fish.
Tank mates
Their calm nature suits a peaceful community. Good companions include tetras, rasboras, corydoras, peaceful barbs, and similarly sized non-aggressive fish. Avoid fin-nippers, which target their long trailing fins, and avoid overly boisterous or aggressive species. For care of a smaller relative, see our honey gourami care guide.
Breeding Pearl Gouramis and Raising Fry
Like many labyrinth fish, pearl gouramis build bubble nests at the water surface among floating plants. During breeding, the male may guard a bubble nest and become protective of the nesting area. A calm, warm aquarium with gentle surface movement and floating cover encourages nesting, but breeding is not guaranteed. After spawning, eggs may be gathered into the nest and guarded by the male. Once the fry become free-swimming, adult care ends and the young need tiny first foods such as infusoria before graduating to suitably sized newly hatched brine shrimp. Separate adults or fry as appropriate to prevent losses.
Frequently Asked Questions About Pearl Gourami Care
Are pearl gouramis peaceful community fish?
Yes, they are generally peaceful with similarly sized, non-aggressive fish, but males can defend their nesting area during breeding.
Do pearl gouramis need floating plants?
Floating plants are helpful because they provide cover and subdued lighting, and may support bubble nest construction. Keep access to the air above the surface open.
What do pearl gouramis eat?
Offer a balanced flake or pellet staple alongside appropriately sized live or frozen foods such as brine shrimp, daphnia, and bloodworms.
