Observe your fish closely. Look for lethargy, loss of appetite, clamped fins, and unusual swimming patterns (like erratic movements or staying at the bottom).
Examine your fish’s body for visible signs. Check for discoloration, cloudy eyes, red streaks, open sores, or unusual growths. These are often indicators of bacterial infection.
Note any respiratory distress. Rapid gill movements or gasping at the surface suggests difficulty breathing, a common symptom of bacterial infections.
Check water parameters. While not a direct indicator, poor water quality increases the risk and severity of bacterial infections. Test ammonia, nitrite, and nitrate levels. High readings can weaken fish and make them more susceptible.
Isolate infected fish. This prevents the spread of the infection to healthy tank mates. Quarantine in a separate tank with clean, well-filtered water.
Consider a professional diagnosis. If you are unsure about the cause of your fish’s illness, consult a veterinarian specializing in aquatic animals. They can provide accurate diagnosis and treatment recommendations.
