i am very much considering getting an octopus(Bimac) for my 90g but i have a question. i did not think of this until now, but i dont want to scare it into inking itself. The 90g is in-wall in my basement. on the wall right next to the 90g is my theatre. when i watch movies, i REALLY watch movies. would the volume, or bass from the stereo scare the octo? or having a projection screen viewable to his tank startle it? <- that can be resolved by fixing a curtin over the tank if i had to. but bass hits and cranked speakers are what i am really worried about now. dont want to kill an animal, or not use my theatre if it is going to be a problem.
