Like Tom's bucket of mud
or vincenz's spawning pool?
Yea I'd go in that direction too, as much as I like Iwagumis I think they're more maintenance and less stability. Carpet plants alone won't do the trick imo. Looks like it's very bright and you get a lot of indirect light too. Emergent plants in the back corner for sure!
Hmm theirs are all against a back window, maybe you'll have to do something a little different?
