I think it depends on the individual puffer.....i have only noticed the puffer peck at the tail of one of the cories, but other than that the puffer on occasion seems to school with the tetras
Some of the tetras have tattered tails..but that's cuz i seen them peck at one another but not once have i seen the puffer peck at the tetras....
