[Jago]

Hi

My tank is around 3 years old.
I’ve got this purple looking tiny mushrooms growing in a few places.
It’s msinly on my power heads.
Can anyone identify them please.

I appears to be a macroalgae of some sort. It's really pretty lol I don't have a positive ID sadly. @KJ you have any idea?
