How do I know if my oscar fish is dying?

You know your oscar fish is dying if it shows these symptoms:

  • Loss of appetite
  • Gasping for air
  • Loss of color from the scales
  • Fins clamped at the side of the body
  • Frayed, injured fins
  • Frantic swimming
  • Abnormal skittish behavior
  • Hiding almost constantly

Oscar fish are usually very hardy and can withstand tough conditions. However, untreated illnesses and parasites can kill even the toughest oscar fish. If you suspect your fish may be sick, treat it immediately and quarantine it so the illness doesn’t spread. Also, make sure to feed your fish properly and maintain the tank regularly to prevent diseases in the first place.
