I've been at college for a few months now and have really been missing my electric catfish - I had to give it up when I left because my current living situation doesn't allow for fish tanks large enough to support one. Anyway, when I get to a position where I'm more capable of caring for one again, I'd like to set up an enclosure big enough to house one for life. But I'd like to make it a riparium or paludarium style enclosure - half filled with water, with branches and other plants above the water line. My question is how large does the enclosure need to be in order to provide the animal with the proper environment for it to thrive. The water will of course be heated and filtered, with appropriate water changes as well. My question starts when looking at the required aquarium size for one of these fish - is the gallonage requirement simply so that the catfish is provided with larger overall tank dimensions, or is it the required number of gallons needed to provide the animal with the correct living conditions?
