Granted, I've only had my P for a week, but he is really inactive. I picked up a Black Mask Elong because they are "supposedly" the most active piranhas in the world. The problem is... he is only active with the light off. He has eaten, but I've never seen it happen, and he doesnt even SWIM with the light on. None of the people I've seen or heard from had to keep their light off to get their P to be active. Does anyone have any tips for this?
