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 guide covers everything you need to keep them healthy.

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. Keep water warm and stable, 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 frozen or live foods such as bloodworms, brine shrimp, and daphnia to enhance color and condition. 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 among the most peaceful of the larger gouramis, which is a big part of their appeal. 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.
