I've recently switched my 300 over to a more peaceful tank. I had been keeping only Central Americans for years. I acquired some nice Pinoy Blue Angelfish from a member here and added a discus, wild Jurapari, and about 30 tetras so far. Really calming to watch and so far I'm enjoying it. (Of course I kept a few of my Centrals in another tank.) Anyway, here it is so far.
