Can anyone confirm what my oscar has?

  • We are currently upgrading MFK. thanks! -neo
if you can, shift him to a hospital tank; means you can treat a smaller body of water, as well as avoid infecting your other fish. Even if its a 20 gallon for him that's fine, since ideally he wouldn't be in it for too long.
 
any new additions to the tank? do worry about external parasites
 
If you do choose meds remember to remove any carbon from your system. There is a sticky thread in the stingray forum with a list of Ray safe medications. Avoid anything with copper
