Honey Gourami Floating Sideways or Upside Down
On Honey Gourami ยท Related disease: swim bladder disease
Signs
- floating at an odd angle near the surface
- difficulty maintaining upright position
- sinking to the bottom and struggling to rise
- buoyancy issues paired with a swollen belly
Possible Causes
Chronic stress from an unsuitable, boisterous community
Honey gouramis are genuinely shy, non-territorial fish, and unlike their more combative gourami relatives they rarely cause trouble themselves; instead they are frequently the victim of it. Housed with fast, nippy, or simply overwhelming tankmates, a honey gourami can become so chronically stressed that its overall condition, including buoyancy control, declines even without a distinct infection.
Swim bladder disorder from overfeeding or constipation
A digestive blockage or trapped gas from overfeeding can compress the swim bladder and tip a fish off balance; because honey gouramis are small and slow, methodical eaters, they are especially prone to missing food at the moment it's offered and then overeating during a later feeding.
Bacterial or parasitic infection affecting the swim bladder
A true infection of the swim bladder organ itself, rather than external digestive pressure or stress, will typically progress alongside other visible decline such as clamped fins or reduced appetite, and needs medication rather than a fasting period to resolve.
Physical injury or congenital deformity
A honey gourami with a spinal or swim-bladder deformity present from birth, or one carrying an old injury, tends to show a stable buoyancy quirk that neither worsens over time nor comes with new symptoms.
At a Glance
| Cause | How to tell | First fix |
|---|---|---|
| Chronic stress from an unsuitable, boisterous community | See explanation above | Reassess tankmates: remove or rehome any fast, aggressive, or overly boisterous species that may be preventing the honey gourami from feeding calmly or resting undisturbed. |
| Swim bladder disorder from overfeeding or constipation | See explanation above | Withhold food for 24-48 hours, then offer a small pinch of daphnia or another fiber-rich food to help clear a suspected digestive blockage, watching to confirm this shy fish is actually getting a share. |
| Bacterial or parasitic infection affecting the swim bladder | See explanation above | Test ammonia and nitrite, and perform a water change, since stress compounds poor water quality in a sensitive, non-aggressive fish like this one. |
| Physical injury or congenital deformity | See explanation above | If buoyancy trouble persists beyond a few days despite fasting and calmer surroundings, treat with a broad-spectrum antibacterial medication in case of infection. |
Fix Steps
- Reassess tankmates: remove or rehome any fast, aggressive, or overly boisterous species that may be preventing the honey gourami from feeding calmly or resting undisturbed.
- Withhold food for 24-48 hours, then offer a small pinch of daphnia or another fiber-rich food to help clear a suspected digestive blockage, watching to confirm this shy fish is actually getting a share.
- Test ammonia and nitrite, and perform a water change, since stress compounds poor water quality in a sensitive, non-aggressive fish like this one.
- If buoyancy trouble persists beyond a few days despite fasting and calmer surroundings, treat with a broad-spectrum antibacterial medication in case of infection.
- If the issue is stable and long-standing without progression, treat it as a congenital or old injury-related quirk rather than active illness.
Prevention
- Keep only calm, peaceful tankmates that won't out-compete this shy species at feeding time
- Feed slowly-sinking or slow-dispersing food so a timid gourami has a real chance to eat its share
- Maintain stable, gentle water conditions, since this species shows stress through subdued color and behavior more readily than through aggression
- Quarantine new fish before introduction to avoid bringing in infections that a non-aggressive fish has no defense against
When to worry, and when to consult an aquatic vet
Because honey gouramis are genuinely shy, non-territorial fish that rarely cause trouble themselves, unlike their more combative gourami relatives, they are frequently the victim rather than the instigator when something in the tank goes wrong, so chronic stress from an unsuitable, boisterous community is a real and species-specific contributor to buoyancy problems here worth ruling in early. A digestive blockage or trapped gas from overfeeding is a more universal cause, and because honey gouramis are small, slow, methodical eaters, they're especially prone to missing food at the moment it's offered and then overeating later or eating less regularly than intended, both of which can compress the swim bladder and tip the fish off balance. A true infection of the swim bladder organ itself, distinct from external digestive pressure or stress, typically progresses alongside other visible decline like clamped fins or reduced appetite rather than appearing as an isolated symptom, and needs medication rather than a fasting period to resolve. A stable buoyancy quirk that neither worsens nor comes with new symptoms may simply reflect a congenital deformity or an old injury the fish has adapted around. Because this species shows stress through subdued behavior rather than obvious aggression, a buoyancy problem that persists beyond a day or two despite adjusting feeding and reviewing tankmate compatibility is a reasonable point to bring in an aquatic vet rather than assuming it will resolve on its own.
