Angelfish acting weird

[vexxiang]

I have a pair of angelfish and they are acting strangely. They've become antisocial, pushing away other fish. One sits in the middle of the tank while the other gently head butts the side. It doesn't seem to mind, and snaps at any other fish that comes near.

Should I do something or let nature take its course?

Possible pairing behavior. What size tank, and what are the tankmates?

Yup. they are feeling the call of reproduction. Your can either separate them, or put other fish in different tanks, to give the lovebirds their space.
