Coralline?

[Nurfed]

This doesn’t blow off with a baster. If this coralline I’ve never seen this color.

Colour looks normal, also comes in green and yellow.
But the more vivid purple looks a bit “hairy” for coralline.

I guess the picture doesn’t do it justice. It’s very red in person

I have that color but it is closer to the top of my tank on the overflows the rest is purple.

Thanks. Now to figure out why my chalice is dying when I brought back an acan from the dead.

But is it solid like rock or hairy.
Had a red pest algae that looked like that once.
Would not even scrub off.
But three large Mexican turbos loved it.

It looked hairy when it first started growing. Now it just looks like rock

Then very possible and a super good sign of water chemistry
