So I've gotten hooked on the idea of building a river aquarium. My pygmy cories love playing in the filter flow so much I would love to build a river biotope around them and upgrade them to some sort of long low aquarium. I've seen these tanks online that have a current going all the way through but I've never seen or understood how. Has anyone done it, seen it done, done something similar, or built a river biotope before?
