White Oscar fin tips?

Looks like early stages of fin rot. If it starts to eat away the tail you will have to treat with meds.
There is a good chance this is natural coloration as well. ex: http://www.fish-keeper.net/Forum/uploads/monthly_03_2007/post-394-1174439713.jpg
Keep an eye on it, If its an unhealthy disease it will be apparent in a couple weeks.

well idk man its a beautiful oscar but other than that i dont know if that would be normal for it or not i mean it could just be growing maybe..idk but good luck finding out

it's normal. i have 2 tiger oscars they both have white outlines on tails. nuthing to worry about

i think its normal to look like that. i have owned oscars before and that's how mine would look when they were growing. not sure about medications for fin rot. the only stuff i do for treating fish is mela and primafix with aquarium salt, works great for me.

Other than his eye being way too big and his caudal peduncle being grossly scrawny from stunting, I don't see anything ailing this fish that you can treat without a bigger tank.

His growth margin ought to be a lot thicker than that, too. The clear area at the edge of the fins indicates new growth. His is too thin. He is not going to live a very good life. Expect chronic ailments and a life of incurable and recurring diseases. Way to ruin an Oscar.

Here's a healthy margin:
At four inches long, the body should look like this.

he wasnt saying it was your oscars fault, he was saying its your fault for keeping it in too small a tank, how long have you had it? as he is right that oscar is sadly already being stunted and needs to be in a larger tank asap, you can start to help it by doing larger, more frequent water changes until you can get the larger tank set-up and yes that white edging on the fins is normal
