Dark red flakey growth, I'D please?

[conflictrealms]

Hi guys,

I've slowly started to get this dark red algae like growth in my tank. It started off on one rock but I've slowly notice speckles of it all over. When the blue light is on a night, it faintly glows orange. Is anyone able to identify what it is? Is it harmful?

Is it hard or soft? It's probably just some type of red macro algae. Maybe this link will help with an ID.

The pics are to blurry to positively ID. It may just be thick, velvety cyano or a type of coralline algae.

The dark red looks like cyano to me, if it is slimy and easy to remove.

The pinker looking stuff looks like coralline, if it is hard and tough to remove

Thanks for the reply so far guys. The dark red is not slimy or soft. It's crispy/flakey. The hermits seem to love it

The dark red may be a form of coraline then.

I Am not sure what it is but i get that in my tank from time to time.. Its hard but kinda has a almost raised like surface..
It does NOT last long My Power Brown tang Seems to seek it out and will devour a silver dollar size spot of this in a day or so.. For some reason it seems to appear overnight.. So my Guess is its Coraline but changed colors or something....
