This place that harleys talking about cant be filled by pecto or any of the big chains. You could easily spend 2+ hrs in there browsing all the tanks. My kid loved going there even if we werent buying anything.
Another vote for Aquascape. That's where I bought 5 roselines. They had them for pretty cheap IIRC. IMO, Aquascape was on par (if not better) than Shark Aquarium for smaller fish. Shark Aquarium shined in the bigger/show fish variety though.
I wish I had something to add but I am in the same boat. I do really like aquascape and he has great fish but the selection just isn't the same as shark.
