I've had my Reds for 7 months and they are as skittish as they were when i got them.

Depending on the individual fish. Most Ps are skittish when young, after about 5" they get used to their surroundings in the tank as well as the activity outside the tank. Try reducing decors and/or turning up the heat in tha tank.

How high? I read in the Saved Topics about turning up to 85 but I didn't know if that was healthy for the piranhas.
