About Swim Bladder Disease
Swim bladder disease encompasses conditions affecting the swim bladder's ability to regulate buoyancy. Affected fish cannot maintain normal position in the water column, floating at the surface, sinking to the bottom, or swimming at abnormal angles. It is particularly common in fancy goldfish and bettas due to their compressed body shapes.
Category: Systemic
Severity: Mild to Moderate
Symptoms to Watch For in Your Harlequin Rasbora
- Floating at the surface unable to dive
- Sinking to the bottom
- Swimming sideways or upside down
- Difficulty maintaining balance
- Distended abdomen
- Curved spine
- Loss of appetite
Causes
Overfeeding and constipation (compresses swim bladder), rapid eating with air swallowing, bacterial infection of the swim bladder, physical deformity (genetic in fancy breeds), temperature shock, poor water quality, and internal parasites.
Diagnosis
Observation of abnormal buoyancy and swimming behavior. Radiographs can reveal swim bladder inflammation, displacement, or structural abnormalities. Assessment of diet and feeding practices. Water quality testing.
Treatment Options
Fast for 24-48 hours, then feed blanched peas (fiber helps constipation). Raise water temperature slightly (78-80°F). Epsom salt bath. Antibiotics if bacterial infection suspected. Lower water level to reduce swimming effort. Hand-feeding for chronic cases.
Prevention for Harlequin Rasbora
Feed appropriate portions (no overfeeding). Soak dry foods before feeding. Provide varied diet with fiber. Maintain stable water temperature. Avoid temperature fluctuations. Select fish with less extreme body shapes.
Prognosis
Good for diet-related cases (often resolves within days). Chronic or congenital cases in fancy breeds may require ongoing management. Bacterial infections have variable outcomes depending on severity.
