What is this

[Jeff Cole]

I think this it's a sponge. Have it growing on my reef at all different depths and lighting. Any ideas? Thanks.

What's the texture of it ?

 

[Jeff Cole]

Like a velvet. No height to it just a coating on the rock

If you can blow it away with a turkey baister thens it’s probably cyno .. if it’s hard and encrusting then it’s probably coralline algae !

Look like Cyanobacteria.

Look like Cyanobacteria.

It's hard and encrusting. Coralline algae can get that dark?
