hey, I live in corvallis and the only lfs around here is animal house. Its a good store, friendly guys. although its a bit tight and dark. and can be a bit expensive. there is one in albany called all for fish that is a nice clean store. good prices, but live stock quality isnt always best. so you can pick and choose :P there are some locals too
30-45min away in Duck country (Eugene) is AquaSerene - decent livestock (including plants) and lots of equipment. Fairly pricey as most places are in Oregon. Can never really find much when I'm in Corvallis.
