Sick tiger oscar HELP!

[Justkell]

Hi I noticed today in my tank at feed time my oscar looked odd and isn't eating (normally the first on to eat) what dose he have? IHow do I treat it? Thank you in advance

Looks like his fins are getting nipped just by glancing at that picture. Can you provide anymore information? Specifics?

 

[SKB]

looks like his fins are being nipped (as said above) or fin rot. What tank mates does he have?

I also see some white patches. Does it look fuzzy or like a wound (indented)?

I had another oscar in the tank that died on Monday I did a ick treatment and changed the water everything is reading normal kit
Now there is just a black convict in the tank with him

He's suffering from fishiskus beatis his buttikus which is latin for someone beat the crud out of him. Just keep the water clean with small daily changes and watch for any other secondary infection.

What size tank is this?
