Urgent help needed, terrible Oscar fight

[alex.walkerrrrr]

Woke up this morning to this, I'm guessing these two had a terrible fight last night, there is another Oscar in the tank that seems to be untouched.

How should I deal with this situation, I've already turned the temp up

Much better looking now but they are still being much more aggressive than usual
