Distribution & Origins
The pearl gourami is native to Malaysia, Thailand and Indonesia on the islands of Sumatra, and Borneo.
They inhabit in slow-moving swamps, rivers, marshes or shallow tropical waters with acidic water. This fish prefers to stay on the top to middle levels of the water.
Pearl gouramis will thrive on flakes, granules and pellets.
Live and frozen food can be given as a treat or to help induce spawning, remember their mouths are quite small so it should be small enough to fit in them. They will also eat algae-based flakes or pellets.
Green vegetables are good to add to vary up the diet.
Sexing the Pearl Gourami
There are several ways to identify a male Pearl Gourami from a female one not only do they tend to be more aggressive, but their colours are much more vibrant and have orange throats and chest.
Male fins are more elongated and larger, and the females have more rounder heavyset bodies. In contrast, the males are thinner, have more angular bodies and have straighter lines instead of curves.
Breeding the Pearl Gourami
The pearl gourami has a very extraordinary and pleasing mating dance. The male builds a nest of small, durable bubbles using plants to bind the bubbles together.
The female will move into position under the nest, then the male curves his body tightly around her, from underneath.
Her body shakes while she expels a few eggs. He then lets her go and picks up the eggs in his mouth as they are sinking, and he spits them into the bubble nest.
The whole sequence is then repeated several times until the female has laid all of her eggs. The male then incubates and guards the eggs until they hatch.
