Heavily planted tank with discus will look amazing! But... It's a hell of a lot of work to keep the plants in tip top condition and do all the water changes to keep the discus happy.
The jar on the other hand.. Not what I would call pretty but very impressive fish! And far more interesting feeding times.
Thats what I was thinking. Are discus really that difficult to keep? Ive never had them before. Also would I be able to put a school of geos with discus?
