Probably won't work as Armatus will swallow an ATF like it was a smelt. My 6" RTG just ate a 4" TATF like it was nothing and still had room to eat more. ATF are pretty dumb when small and just tend to dash around the tank like a minnow. Even my 12" Vittatus gets the chase put on him by my pbass,indo and RTG. He's always having to look behind his shoulder!
