coraline help here!!!!

[Gian081]

after some months of establishing my reef tank im getting big spotted things in the rocks and the back of the glass. The things is that is not purple, is a red color. Some spots are a normal red and other are quite of wine color. I like to know if coraline have this kind of color to or if this something bad.

Thanks

Really the only way for someone to ID what you're seeing is with a good picture - anything else is just a guess, which doesn't help you much

it sounds like coraline, it can be red
