I love Bolivian Rams! I just bought 3 of the cuties recently. In my opinion Tetras aren't basic, while the Neon in common, there are many Tetras that are new to the hobby or underused.
There are beautiful sparkly Diamond Tetras, great colors in the Emperor Tetras, interesting pattern of the Rummynose Tetras, and the awesome Colombian Tetras with their visible teeth. Tetras often get a reputation of being starter fish or as you said "basic" aquarium fish, but there are many different types of Tetra and they all add a bit of color and flash to a tank.
Don't sell Tetras short, do some basic searches and see whats available in your area. I believe that a small school of 6 Tetras of your choice would be a great addition to your tank.
