I have stopped in a couple of times to check it out. It has an open layout with a lot of potential. That being said, they are still fairly green in this new location, and though I did stop in Vienna Aquarium back in Vienna, its been a while and the folks here may be different. I for one, having moved out west, am rooting for them. I've gotten good and bad advice from all the stores - its about the people working their and when you catch them. Fish I've gotten at Petco have stayed with me for years and fish from a "great" LFS have not lasted months. Advice in this hobby has to be taken lightly and test against one's owns experience as their is no silver bullet. Ultimately, a little more competition is good for us all and Leesburg needs a good LFS!
