Ok, cool... I thought that Coraline was mostly pink/purple, so am just wary of anything unknown (which admittedly is quite a lot given that this is my first saltwater tank haha).
The guys down at my LFS don't seem to be worried about anything. They just said to leave it all alone, no water changes, don't worry about algae, critters etc. You can just get paranoid somethimes when you read about things that you HAVE to remove from the tank before they spread/etc
Can't wait until I get to the point where I can just know what everything is and whether or not any action is required
