I was going to make a joke about making sure the fish were in the sweet spot, but this thread has turned serious. I assume fish don't have ears and somehow the vibration is scaring the sh*t out of them. They probably feel kinda like an achovy about to be attacked by a killer whale. I never liked anchovies, but feel kinda sorry for the rest of the little finned guys. I'm a tad of a hunter so no animal rights stuff here, but makes you hope that you don't come back as an audiophile's pet fish.
Aquariums and Audio Equipment
I'm dying to shift my audio equipment closer to one one side and center a 80 gallon reef aquarium between my revel studios. However, I'm getting nervous about the potential problems this may present (flourescent bulbs, potentially noisy pumps, caustic salt water, bubbling of jets, etc). Anyone have experience with mixing aquariums with audio equipment?
