Help Identify Red & White Stuff

[Moonrock]

i have a mostly sps tank and have found a spot on my rock with some red stuff growing on my rock along with some white stuff growing in another section on the same rock. Its 10inches apart but im not sure what it is.

Wasnt sure if i should have posted this in the coral or fish ID section since its neither.

Anyway, any help would be appreciated.

I'm not really seeing anything in the first picture, but that white stuff in the second is just a harmless sponge.
