Only way I'd consider adding the atf to the tank is adding them all so any aggression will be dispersed, and maybe if they school some, the armatus may be a little intimidated.
The trio is still in a 8x3. The biggest is still in a 6x2.
Still haven't had the balls to toss the big one into the big tank.
The big tank sucks cause there's 2 Armatus, 2 Dorado, he's immediately the minority without the others. Add the others and the big tank inhabitants will think its a turf war.
I meant put. And oh it looked like they were in the big tank, and you make a good point, but I think if you were to put them in there they'd have to settle the hierarchy but unfortunately they all have deadly dentures.
