I have a pinkish/red growth coming on the underside of my rocks where there is no light and no other growth whatsoever. Does anyone have any idea what this might be. I know this isn't a lot of info and I have tried to get a pic but none will turn out good enough to make anything out.

Sounds like Cyano bacteria to me. What are your ammonia, nitrite, and nitrate levels at?
