Indoor pond stocking suggestions

[Nik_n]

I was considering setting up a low tech (no filter or heater) pond inside my house. I'm going to use a big plant vase (don't know about the volume yet). It will be heavily planted with emersed and floating plants. Don't know if I will use any aquatic since I won't be able to see them and they won't get enough light. The temperature of the tank will be about 18-22 °C. 

I was considering some cold water fish and this is what I came up with 

• white cloud mountain minnows 
•  Endler's live bearers
• Rosie barbs 
• CPDs 

I might make it a species only if I want to breed the fish. 

Which one would be the best type to keep in a setting like that, by that I mean which ones would be the most colourful from the top?

Definitely the white cloud minnows. I think everything else would struggle in a setup like that. I would put at least a small sponge filter in the bottom cause you could easily hide the airline tube
