Same here with the red. My silver also gets spooked from the egg grate fixtures or rather the light that reflects off of the egg grate fixture I have over my aquaripond. So now, I turn off all of the lights when I remove them and even if he sees them from a distance, he still flips out! He doesn't like anything fast moving either...at least nothing that is bigger than he and he's probably 30in now.
Silver arowana is skittish fish. Doesn't matter what color you wear (or if you wear anything ) silver aro goes crazy whenever it feels like! And when silver goes wild, everyone in the tank goes wild!
