Goldfish - Health

How do I know if one of my goldfish is ill?


You should check your goldfish each day for any signs of illness. These might include the following:

  • Gasping at the surface
  • Rubbing against objects in the tank
  • Lethargy
  • Not coming up to feed
  • Swimming in an unusual way
  • Change of colour
  • Lumps
  • Ulcers
  • “Cotton wool” growth
  • Ragged or damaged fins

If you see any of these signs, visit your vet straight away. There could be other signs of illness, not on this list, and any change in behaviour should alert you to the possibility of illness. 

What should I do if I think one of my goldfish is ill?


If you are worried about the health of any of your goldfish, it is always best to contact your local veterinary practice.
