Yah, I'm not a big fan of those 3 but they are beautiful. The reason I'm "not a big fan" of neon tetras is cause 1st they are so common and I want to try and stay away from the "classic fish" of the home aquarium... 2nd reason is cause their colors are infused with jellyfish... I forget what part of the jellyfish they use but they infuse it to "beautify" themActually there are also many centerpiece fish for you to choose. Some of them are:
1)Apistogramma Borelli
2)Honey Gourami
3)Killifish - Bluefin Notho
Avoid Golden Panchax Killifish that will grow large and can eat small fish.
