It's tiny! 4.3gal, fresh water. Has four little pigmy corydoras and one Otto catfish to keep things clean! I want bigger, but I have a small apartment right now and I think it would be unwise to move with a large, heavy aquarium. But I love this little one. It's like a 1x1ft river bottom in a far away creek in South America. I like to watch the microfauna play in the red root floaters and the fish go after the algae and such. So far, they haven't even touched man-made food. They just want the algae I've been growing for a few weeks :)

This is the first aquarium I've also had since I was a kid, and I love it :)
