I'm getting 4 Gatfs around 4" I what to keep them in the same tank, 75 gallon grow out tank r their going to kill or bite at each other? Anyone keeping them together without them killing each other?
 
Always keep feeders in the tank, or they'll turn on each other, or hunt the weak one
 
Even with feeders I'm sure they'll fight. Unless the tank is much bigger expect injuries. IME when they have a lot of room they don't fight as much. I have four 4" ATFs in a 680g tank and they still nip every once in awhile but not as much as they did in a 150g.
With a fish with the grill in front, and a speed of a torpedo, there's always injury. My guess, your ATF nipping at each other, because you don't have feeders in the tank, don't always have food in the tank.. I don't know if you notice, but whether you have 4 ATF in 680 gal tank or 150 gal tank, they don't stay one at each corner. They gather together.
 
I just never try 4 gatf at at the same time and in one tank. I know they act like piranha. I seen a group of 8 piranhas lowly started to eat each other until there where only 2. But I will keep feeder in there at all time. There a guy on YouTube in china that has 4 huge gate 1 huge vatf in the same tank. Will they mellow out when bigger?
 
They are always well fed. So fighting is not because of hunger. It's just their nature.

Yup, mine do this as well...When they nip at each other it is clearly not feeding related. So far all I see is the occasional spot of missing scales or slight tear in a fin. Mine also seem to swim together about 50% of the time and stay to themselves the other 50%.

Whether it's hunger or their nature, having feeders in the tank will give them chance to pick on feeders than on each other... Besides, they're always well fed is just your thought/assumption. It's hard to sit by your tank and feed them 24/7

They may not mellow out when they get bigger. However, they may defend themselves better when they get bigger, so they don't mess with each other much.
