Hi, for all of you who gave me advises, thanks, but my oscar didn't make it, yesterday when i return home from my job, i found him upside-down at the botom of the hospital tank....
The reason why i'm still having this message is another question....
What should i do with the water on both tanks, the tank where he lived, and the hospital tank, should i take all the fishes out and change the water, should i change a percentage of it....? should i leave it the way it is, i changed the 25% of water last week----but with the oscar[sup]t[/sup] still living there....
