What does it mean when a fish can’t swim up?
Negative Buoyancy Disorder
Fluid can be ingested through the pneumatic air duct that connects the swim bladder to the esophagus while eating. When the fluid displaces air within the swim bladder, the fish has a difficult time maintaining neutral buoyancy in the water column, but typically, it has normal posture.
How do you know if a fish is struggling to swim?
If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress. Talk to your veterinarian about treatment and look into what may be causing the stress and alleviating it.
