The healthy licorice gourami at a glance
A healthy licorice gourami is a small, quiet fish with a surprisingly rich appearance. Males in good condition show deep brown to near-black bodies with fine patterning and fins edged in shimmering blue-green, while females are usually softer in tone but still clear-eyed and full-bodied. The fins should look whole and smooth, not pinched tightly against the body, and the eyes should be bright and level rather than cloudy or sunken. Nothing about a settled fish looks frantic: movements are slow, considered, and close to cover.
Behaviour among plants and leaf litter
Licorice gouramis come from dim, plant-choked blackwater, so a healthy one spends much of its day hovering under leaves, drifting through stems, and inspecting leaf litter for tiny morsels. Hiding alone is not a warning sign for this species — it is normal cover-seeking. What matters is the pattern around it. A well fish still changes position, claims a small territory, and emerges when food arrives or when the tank quiets down in the evening. Constant wedging in one corner, lying tilted on the substrate, or failing to react to movement near the tank is a different picture and deserves attention.
Males in condition may display to each other or to a female, flaring their fins briefly and showing their strongest colour. That short, controlled display is a good sign; relentless chasing that leaves another fish unable to feed or rest is a social problem, not vigour.
Feeding, breathing, and body shape
Appetite is one of the clearest windows on this species. A healthy licorice gourami hunts: it eyes a morsel, edges forward, and takes tiny live or frozen foods eagerly, then keeps foraging. A rounded, gently filled belly after feeding is normal, while a hollow belly, a knife-thin back, or repeated spitting out of food suggests the fish is not getting or not taking enough. Offer foods small enough for its tiny mouth and watch that bolder tankmates do not finish everything first.
Like other gouramis, it has a labyrinth organ and will rise now and then for a calm sip of air. Occasional surface trips are expected. Repeated gulping at the surface, rapid gill movement while resting, or hanging just under the surface for long stretches can point to low oxygen or irritated gills and should prompt an immediate check of temperature, filtration, and recent water-test results.
Colour changes and surface details worth noting
Colour in this fish is a mood and health gauge. Settled males deepen in colour during display and feeding, and a fish that has coloured up since arriving home is usually a fish that feels secure. Persistent fading to a pale grey-brown, dark stress blotches that never lift, white patches, fuzzy growths, red streaks in the fins, or tiny spots scattered over the body are all changes to record with the date you first saw them. Scales should lie flat, the skin should look smooth, and there should be no sour or rotting smell from the tank water.
When a licorice gourami needs help
Contact an aquatic veterinarian or an experienced fish-health adviser if a licorice gourami stops feeding for more than a day or two, breathes rapidly at rest, loses colour and stays hidden through feeding, or shows spreading patches, sores, or fraying fins. Because these fish are so small, decline can be quick, and a clear written timeline — when appetite changed, what the water tests showed, what changed in the tank — is far more useful to a professional than a general report that the fish seems off. Saving that timeline, your test results, and the fish's feeding history in KinsLe's Pet Passport means the whole story travels with the fish whenever advice is needed.
