About 6" smashing tilapia. I usually only cut long thin pieces so that they can get more full on the first strike and fill in with the rest with smaller pieces. Thats usually how i powerfeed my all ATF's for bulking.
He's a belter. Not sure I have seen a brevis before.
You feed like I feed mine that first bit of food that goes in the tank is the tigers so I always put the biggest fish in first as he'll strike it and eat it the rest are cut in half
