I think this tank by heiko bleher comes close to what a discus habitat should look like. I can picture discus, instead of the angelfish. Also imagine a large arowana patrolling the surface of this huge tank and some catfish on the bottom amongst the leaves. Also it would be a great setup for many of the large cichlids.
I think the' flooded forest' would be a great name for a simular setup. To me, this tank is a great inspiration. Should you ever come across this page heiko "tank you very much"...dankeschoen!
