I need help to identify a show piece fish for my tank, which makes people go whoa when they look in. I am currently failing to location a species that fits the bill:
- Not a a discus
- Cannot grow bigger than 10cm
- I guess not a cichlid because of my current inhabitants
- Is a stunner (subjective I know)
When I look in the marine fish sections and I see a plethora, freshwater... erm not so much

Any ideas are appreciated?
Warm regards,
James
