A Guide to Keeping Pearl Gourami

The Pearl Gourami (Trichogaster leerii) is a popular and peaceful freshwater fish known for its stunning appearance and calm temperament. Native to Southeast Asia, it gets its name from the intricate, pearlescent spots that cover its body, resembling a dusting of tiny pearls. Its long, thread-like pelvic fins are also a distinctive feature.

Tank Setup and Care

Pearl Gourami are generally placid and can be a great addition to a community tank, but they do have specific needs to thrive.

• Substrate: A dark-coloured substrate will help to bring out their vibrant colours.
• Decorations: Provide plenty of hiding spots and visual barriers using driftwood, rocks, and caves. They are also labyrinth fish, meaning they have a special organ that allows them to breathe air from the surface, so it’s important to leave a small gap between the water’s surface and the tank lid.
• Filtration: A gentle filter that doesn’t create a strong current is best, as they are used to slow-moving waters.
• Plants: Live plants are highly recommended. They particularly enjoy floating plants like Frogbit or Dwarf Water Lettuce, which provide cover and diffuse the light.

Diet and Feeding

In the wild, Pearl Gourami feed on a variety of small insects, crustaceans, and plant matter. In the aquarium, they are not fussy eaters.

• Flake and Pellet Food: A high-quality flake or pellet food should form the basis of their diet.
• Frozen Foods: Supplement their diet with frozen foods like bloodworms, daphnia, and brine shrimp to ensure they receive all the necessary nutrients.
• Live Foods: Live foods like fruit flies or mosquito larvae are a special treat that can help to bring out their natural feeding behaviours.

Tank Mates

Pearl Gourami are peaceful and get along well with many other fish. Good tank mates include:

• Rasboras
• Corydoras
• Small Tetras (like Neon Tetras or Ember Tetras)
• Plecos (small species)

Avoid keeping them with aggressive or fin-nipping fish, as their long pelvic fins can be a target. Male Pearl Gourami may show some territorial behaviour towards each other, so it’s often best to keep only one male or a single pair in a smaller tank.
