I think a planted Discus tank is one of the most butiful sights in all of fish keeping, and those that choose to keep them in bare tanks are missing half the potential of one of the worlds most beautiful fish. But if you want to grow dinner plates bare tanks are the way to go. If you want big discus in your planted tank grow them in bare tanks and then move them to the display tank. Otherwise just grow them out in the planted tank.
I have been keeping planted discus tanks for years. I posted in other threads that I've always drawn insperation from the Takashi Amano type tanks. Rather than write a book here reasearch the above, there is a welth of information to be had.
I do keep loaches, Botia Sidthimunki the dwarf loach. These are great little fish they eat snail eggs and tiny snails before they grow. They are not too easy to find and are not that cheep but great for a Discus tank. Stay away from Ottos they are slime suckers. A bushy nose pleco is a good choice for your tank. I also add Caridina japonica, (Amano Shrimp) to the tank for algea duty. All your Tetras are fine, and I don't think your Rose Line Shark will bother the Discus. Just keep the water clean and feed good food. I have never been big on using beef heart. A good sinking pellet of apprprate size (NLS Thera A is good) along with some chopped earth worms and minced shrimp. Good luck, your going in the right direction, do the reasearch and you'll have a great Discus tank.
