Would this work?

How big is your tank?
- more visual barriers
- more dats
- bigger fish then tiger barbs to spread out aggresion if you can't get any more dats
- Wait it out a couple more days and see if your AT settles down
- divider

Those are some options, the 2nd and 3rd may not be an option if you have no tank room.

hmmm There these 6" NGT / IT at my lfs that I could get, but Im not sure if they will cause more problem or not

The AT is smart too, anything that is bigger than him (all of them) he wouldnt touch

The IT is hiding behind the powerhead and 60G is already a small tank, I dont think adding a divider is ideal... Probably if this continue, I might take it back and trade for a bigger IT

I can get 6 more Geophagus Surnamese for $50 but then, I am scare they will fight among themselves

Yeah...if they can fit in their mouths you can be pretty sure they will eat them. Do you have a lot of visual barriers and hide spots??

kinda, but the stupid fish knocks them all down
