Clowns fighting...
 

Help...I have 3 small maroon clown fish that I purchased about 3 to 4 weeks ago. Up until yesterday all 3 would hang out in one corner of the tank (they are the only fish in a 20 gal. tank). Now, 2 of them are in the corner and the other has been kicked out of the group. One of the fish of the pair (the supposed male) keeps going out a trying to fight with the one that was kicked out.

Not sure what to do.....???? I don't want them to kill each other....

Take the 3rd one out. Appears that the 2 have paired up, and the 3rd will be a goner unless you move it out of the tank.
