I think this is one of my favorite stores in Portland, its not very big but they have good prices, the only downfall is they could do a little more tank maintenance. But This is where I got my black aro and my hystrix ray, they also have quite a few custom built tanks that aer nice.

Well this one seems to have moved or went belly up because the store is empty now
