mirror

Can a mirror be used to draw out a Nuchal Hump from a male angelfish? I was wondering because it works for Flowerhorns so I just wanted to know.

If I put a mirror in with a Thai Green Texas every once in a while, will it help it's nuchal hump grow?

I tried a little mirror grooming today. Just a quick 20 minute session to see what it's about. I'll post pictures to show the changes. These were right at 24 hours apart. Nothing changed besides the mirror grooming.
