Just want to know if i.should be worried

[braden18]

I found this white stuff growing on the rock of my devils hand, does anyone know what it is?

The flat ones should be calcareous algae
But if there is calcium algae, it should turn red in a week or two.
And those with a somewhat three-dimensional tube shape may be Vermetidae or tubeworms.

It's solid like a rock to be honest I just noticed it

Should I be worried

Calcareous algae have relatively little impact on coral growth.

Should I be worried

Just leave it and observe it first. If they are calcium algae, it won't be a big problem.
