I have two tomato clowns and i have two Silver Mooneys. well one of the Clowns will get air in its mouth and go and find one of the Moonies and blow it into the Mooneys face. sit there looking at the Mooney like tempting him/her to do something. or maybe just laughing at him. after about 5 seconds the clown will go get more air and do it again... now if i was that Mooney i would take it personal and kick that clowns butt.
