Overview
The pearl gourami is one of the most elegant fish in the hobby, wearing a coat of shimmering white pearl-like spots over a soft brownish body. It comes from the slow, plant-choked waters of Southeast Asia, including Thailand, Malaysia, and the islands of Borneo and Sumatra. During breeding season, males light up with a bright orange-red throat that glows against all those silvery pearls.
Like paradise fish and bettas, pearl gouramis are labyrinth fish that can breathe air from the surface, letting them thrive in warm, still water. One of their most charming features is a pair of long, thread-like fins hanging beneath the body, which they use like feelers to gently touch plants, objects, and even tank mates. Calm and peaceful, they make a beautiful centerpiece for a gentle community tank.

A coat of pearls
The pearl gourami is named for the pattern of round, shiny white dots scattered across its body and fins, which really do look like tiny pearls. A dark line runs from the nose to the tail, adding to its graceful, refined look.
Feelers like fishing lines
Beneath its body a pearl gourami has two long, thin fins that trail like threads. It uses these feelers to touch and explore its surroundings, since the murky waters it comes from can be hard to see through.
Breathing at the top
As a labyrinth fish, the pearl gourami has an air-breathing organ that lets it gulp oxygen from the surface. This is why it can live comfortably in warm, still, low-oxygen water where many fish would struggle.
The blushing male
When a male is ready to breed, his throat and chest turn a glowing orange-red. He then builds a floating bubble nest and guards the eggs inside it, a behavior shared by other labyrinth fish.
A peaceful centerpiece
Pearl gouramis are gentle and a bit shy, so they do best in a calm tank with plenty of plants to feel safe. They mix well with other peaceful fish and make a lovely, eye-catching centerpiece for a community aquarium.

Frequently asked questions
Why does my pearl gourami touch things with long threads?
Those threads are special feeler fins. In the murky water where pearl gouramis live, feeling their way around helps them explore plants, objects, and tank mates by touch.
Are pearl gouramis aggressive?
No, they are among the most peaceful gouramis. They can be a little shy, so a planted tank with calm tank mates helps them feel comfortable and show their best colors.
Why is my gourami gulping at the surface?
Pearl gouramis are labyrinth fish that breathe air. Coming up for a gulp at the surface is completely normal and part of how they survive in warm, still water.
How do I tell males from females?
Males have a more pointed top fin and, when ready to breed, a bright orange-red throat. Females are usually a bit rounder in the belly with a plainer chest.
