Short description

The Pearl Gourami are a very peaceful species however you may find that having ore than one male in the tank may lead to territorial issues. They are great for the community tank as they tend to leave other species alone. They can be intimidated by aggressive species so always keep them in a peaceful community. The Pearl Gourami has very little requirements when it comes to furnishing the aquarium, plants can be added and provide some hiding places by the addition of rocks or wood. Make sure that you leave open swimming spaces and keep the water flow to a moderate rate.


They are certainly not fussy when it comes to eating and once settled in the aquarium should accept all foods offered. Use a quality flake for the staple diet but also offer them treats of live or frozen foods.


Males display a much brighter colouration than the females and have a throat colouration of red or orange. They will also develop extended finnage as they mature.


Pearl Gourami are bubble nest builders, the male will build his nest at the water surface and then entice the female over to encourage her to deposit her eggs there. Adding floating plants will help greatly with this process and he may even use leaf fragments to give the nest more strength. Keep the water flow turned down low and once ready the female will approach where a courting ritual will take place. The fish will entwine and the eggs are released under the nest where they will float upwards. When spawning is complete, remove the female as the male assumes the care and the female will be chased away no longer required by the male.

The eggs should hatch after a day and once free swimming can be fed on newly hatched brine shrimp or infusoria.
