You can tell your Oscar fish is sick by observing changes in behavior or appearance. Signs of illness include lack of appetite, lethargy, unusual swimming patterns, or visible abnormalities such as lesions, rapid gill movement, or discoloration. Additionally, if the fish is isolating itself or exhibiting fin clamping, these may indicate stress or illness. Regular monitoring and maintaining good water quality are essential for their health.
