Honestly, I never really thought Tetras were that cool compared to some of the other small schooling fish. But I am creating an Amazon River Basin biotope aquarium soon and I have found two species of Tetras that I really like. Would you suggest Emperor Tetras, or Rummy Nose Tetras? I feel that both are equally interesting for different reasons. I'd like to hear the opinions of other members whether they have both, just one species, or have seen them in an aquarium before. Both would be awesome, but at my LFS thats about $20 per school of fish. I am interested to hear what other members think of these fish.
