I've seen these before, but never really investigated them - they're certainly cool looking! Would give your tank that "wow" factor, @Rocky998 , without the frenetic energy and colour that you seem to want to avoid?This is a legendary dutch store that have a video of one of the species but very nice video as an example

But I know nothing about these types of fish, and I'm curious now! Want to find out about their normal habitat and how they live. Cool suggestion!
