I walked by my tank last night to see one of my rocks covered with what looks like aptasia but really small, is this tube worms or some type of polyps? does not look to be feather dusters IMO. also what is that algae growing on the rock is it bad and do i need to remove it asap? Thanks so much.

agreed. at least some kind of star polyp.

i wonder if they are bleached, or if thats the natural color?

It looks exactly like some GSP I have in my tank. One of the rocks it was growing on was moved and light deprived for a few months. Since upgrading to my 75g it is now exposed to the light but bleached.

hmm interesting, was hoping that what it was and not something bad, thanks for the help.

They'll probably be very similar to the color they are now.

encrusting gorgonia,,,i have had it for years, great stuff

The macroalgae is halimeda.

Agreed on the halimeda. If you like the look of it keep it but it is a calcium hog

I am not so convinced that the other is GSP but I can't offer any suggestions as to what it might be. The only reason I am not convinced is beause it usually has a solid mat.
