What is this growing on my Chaeto?

[Admiraltian]

There's quite a lot of little red dot thingy growing on my chaeto (Pls see pic).

Wondering is it harmful? Should I remove them or can juz leave it alone? If removing, is there any method of separating the red stuff from the chaeto other then throwing away the whole bunch?

Pls help, thanks.

Is it look like this? Cheers...

[Admiraltian]

Not really, it's more like redish to purple color, I thinking could it be cynaobacteria or coraline algae growing on my chaeto too?

Anyway here's another closer look at it, hope it helps to see the problem,

Looks like some tiny serpulid worms.

Actually the red dots on the chaeto is not moving, just sticked to it. Dunno if it's growing, quite a lot.

Look like cynaobacteria to me. Does the cynao grow in your display tank?

[Rukas]

hmmm.. i am thinking, could be cyano, any outbreak in DPT? possible to take some out and try the cyano removal methods?

[Admiraltian]

No cyano in my DPT. Cyano should be easily brush off but this one juz stick to my chaeto like a leech.

The little red dots seems like some sort of red hairy algae growing on the chaeto strains. Headache, dunno how to get rid of it.

[Admiraltian]

I've just trimed my chaeto, Tear out about 1/3 of it and threw it away (Dunno if it's the right thing to do?). The remaining still covered with a little of the red dots stuff. Hope they dun get infested and overrun by the red dots again. I think most of them r a type of red hairy algae, while some is coraline cos it looked purple to me.
