Overview
The dwarf gourami comes from the slow rivers, ponds, and rice paddies of South Asia, in countries like India and Bangladesh. Males glow with shimmering stripes of red, orange, and electric blue, which makes them one of the most eye-catching fish for a small community tank. Females are a plainer silvery color.
Like all gouramis, this fish has a special organ called a labyrinth organ that lets it breathe air from the surface. That is why you will often see it rise up to take a gulp of air. Dwarf gouramis are peaceful and a little shy, so they do best in calm tanks where they can glide slowly and explore at their own pace.

Water and tank
A dwarf gourami is happy in a tank as small as 10 gallons. Because it breathes air from the top, the water surface should be calm and not too choppy, so a gentle filter flow is best. Warm, stable water keeps this sometimes-delicate fish healthy.
Aquascape and setup
These shy fish love a heavily planted tank with plenty of cover to feel safe. Floating plants are especially good, since they calm the surface and give a male a place to build his bubble nest. Soft lighting and some hiding spots help a nervous gourami settle in.
Diet
Dwarf gouramis are easygoing omnivores. Feed them quality flakes or small pellets as a base, plus frozen or live treats like bloodworms, brine shrimp, and daphnia. A varied diet keeps their bright colors glowing and supports their overall health.
Tankmates and temperament
Peaceful by nature, dwarf gouramis fit well with other calm, small fish such as tetras, rasboras, and corydoras. Avoid fin-nippers and pushy species that would bully them. Two males may squabble over territory, so a single male or a male-female pair is usually best.
Bubble-nest builders
When ready to breed, a male dwarf gourami blows a raft of sticky bubbles at the surface, often among floating plants. He guards this bubble nest carefully, tending the eggs and newly hatched fry. It is a fascinating behavior you can watch right in a home tank.

Frequently asked questions
Why does my dwarf gourami swim to the surface to gulp air?
This is normal and healthy. Gouramis have a labyrinth organ that lets them breathe air directly, so they rise to the top for a gulp now and then.
Can I keep two male dwarf gouramis together?
It is risky in a small tank, because males can be territorial and fight. A single male, or a male with females, usually keeps the peace.
Are dwarf gouramis good for beginners?
Yes, they are peaceful and easy to feed. Just buy healthy stock, keep the water clean and stable, and give them plenty of plants to feel secure.
What tankmates suit a dwarf gourami?
Calm, small community fish like tetras, rasboras, and corydoras. Avoid fin-nippers and aggressive fish that could stress this gentle, shy species.
