  • A keeper interested in observing bubble nesting

Think carefully if

  • Your tank has aggressive or boisterous fish
  • You plan to keep several males in a small tank
  • You keep very small fish or shrimp

A graceful Southeast Asian gourami with a pearl-spotted body. Calm for its size, it makes a fine centrepiece in a medium community aquarium.

Appearance and Identification

A silvery brown, flattened body covered in pearl-like spots, with a dark line along the flank. Mature males have orange or red throats and extended dorsal and anal fins.

The pearl-spotted pattern and dark flank line make this one of the easier gouramis to identify.

Males are more colourful, with orange or red throats and extended dorsal and anal fins. Females are duller and plumper.

Provide tall plants and floating cover to break sightlines. Keep the flow low and the surface accessible, and use a lid to keep the air warm.

Behaviour and Tankmates

Calm and graceful, moving slowly through the water and feeling its surroundings with long pelvic fins.

Keep one male with one or more females, or a mixed small group in a larger tank.

Males are territorial toward each other and can be rough with females during breeding.

Good with medium-sized peaceful fish such as larger tetras, rasboras, and corydoras. Avoid aggressive or boisterous fish and fin nippers. Very small fish and shrimp may be eaten.

Water Parameters

Temperature
24–30 °C
pH
5.5–8
GH
2–30
Stability importance
Normal

Adapts to a broad range of water. Warmer temperatures suit this fish, so plan tankmates to match.

Parameter caveat
Gouramis breathe air from the surface, so keep the surface accessible and the air above it warm with a lid.

Feeding

Diet types
Insectivore, Omnivore
Feeding frequency
Once or twice daily
Preferred foods
  • Small floating pellets or quality flakeThese fish feed readily from the surface. Choose a small size and feed sparingly.
  • Frozen or live daphnia and brine shrimpOffer a few times a week for variety and condition.
  • Frozen bloodworm or mosquito larvaeUse as an occasional rich treat rather than a daily food.

An omnivore that takes surface foods, small invertebrates, and plant matter.

Add vegetable or spirulina flake to the rotation for balance.

Breeding

Breeding type
Bubble Nest
Breeding difficulty
Moderate
Brood or egg count
200 to 300 eggs
Incubation
2 days
Parental care
Bubble-nest care
Baby foods
  • Infusoria or parameciumEssential for the first days, because labyrinth fry are tiny and cannot yet take larger food.
  • Vinegar eels or microwormsIntroduce as the fry grow, and offer in small amounts to protect water quality.
  • Newly hatched brine shrimpIntroduce once the fry can swallow it, usually after one to two weeks.

A bubble nester. The male builds a nest of bubbles under floating plants, and spawning happens beneath it. Remove the female after spawning, and remove the male once the fry become free-swimming.
