Initially I only shopped online at The Tech Den because I noticed they re-homed fish. (This impressed me because I'm over other creatures being seen as valued pets but fish being seen as disposable decorations fed by an unethical industry that fails to inform people of even basic care). Then the Tech Den turned out to consistently have high quality product, really competitive prices & great customer service. Their advice is real & educated - not the invented quick sale advice you get at so many aquarium outlets. And they still re-home fish. So it's now the place I look first when I need something.
