My tank has been settled for some few months now and suddenly, out of the blue, my Penguin tetras have started to attack one another and other fish.
I've had the 5, as a settled group, for about 3 months now, and two have suddenly begun attacking the others, killing one and now picking on another one.
One seems to "defend" the left side of the tank, the other seems to "defend" the right.
Any ideas what this could be? I thought Penguins were quite placid fish.
