Red lines in tank

[af0929]

Pls help! This morning i woke up to find my yellow tang dead. We have had him for about 6 months so it was just out of no where. There are red lines on the side of the tank. I have 2 tanks and i have never seen them in the other tank. Is this normal?! I couldnt get a good picture of them....

Hmm, is the line straight? could it be some sort of cyano? not sure.. sorry : <

worms? do the line move at all?

 

[af0929]

No they arent straight. They kinda branch off like a vine as they grow. I scraped off the glass and you can kinda see them coming back now. I think they may just be some form of algae but its making me nervous

 

[BIGgourami]

does it look kind of like this?

I think its red slime algae...was it easy to scrape it from the glass?
