Animals can't tell their owners when they feel unwell, and fish don't communicate with their owners at all.
But you still can see the signs that your fish isn't right, and take good care of your pet.
Here are some of them.
Loss of appetite
If your fish is not eating or showing reduced interest in food, it may be a sign of an underlying health issue.
Monitor their feeding habits closely and observe if they are actively avoiding food or spitting it out.
Physical abnormalities
Look for any physical changes in your fish.
This can include visible wounds, sores, growths, lesions, discoloration, or fin deterioration.
Changes in swimming patterns
Notice if your fish is having difficulty swimming, is floating or sinking uncontrollably, or has trouble maintaining balance.
Labored breathing
Observe your fish's gills and check if they are breathing rapidly, gasping for air at the water surface, or exhibiting signs of labored breathing.
Rapid or irregular gill movement, flared gills, or coughing can indicate respiratory distress or poor water quality.
Erratic or excessive rubbing
If your fish is constantly rubbing itself against objects in the aquarium, it may be a sign of skin irritation or the presence of parasites.
Changes in waste production
Any significant changes in the color, consistency, or frequency of their waste can be indicative of digestive issues, infections, or other health problems.
