okay this happend quite a while ago just forgot to post, so i have 3 peacock bass and 2 payara(scomb) in my tank.
One day its there live food day and well i got grab 30guppies and plot em in the tank. They start to devour the guppies and then it comes to the last few, the scomb spotted one and so did one of my peacock bass (It was the same guppy they both found) they both got ready to charge and so they charged. The outcome was the scombs teeth in the peacock basses face and the peacock basses jaw in the scombs mouth lol... but then they let go of each other and went on nothing happend to either of emm no puncture wounds on the bass and no scrap marks on the scomb all was well just pretty cool to see happen.
. Just next time ill add a lil more feeders 
the guppy lived but later got eatin by another peacock bass.
