It's a less known fact that the Epicenter of the quake was in Reseda and not Northridge... at the end of Elkwood St. I live w/ my parents at the time in Saticoy - Elkwood is walking distance from our house so I can pretty much say that I was in THE epicenter when it happened.
I had a 30 gal freshwater mollies/guppies at the time.. other than water spills on the floor, nothing else got damaged. The tank used to sit on top of an old furniture. If I had the setup I have today, it would've been a different story.
