Should I be worried? I have about 5 of the first pic on my GSP(now in quarentine) and about 1000 of the little "white dots with legs". They look like 1mm brittle stars.
:sad: is there a cure? I cant tweeze them out of the GSP.
have pic 1 no worries, only seen pictures of your pic 2 so won't comment

No worries? I heard they sting like crazy and will actually kill some corals. Also read they spread.
pic 1 is a digitate hydroid and pic 2 is another type of hyrdoid
I have the digitates in my tank as well, a few, and they don't really seem to do much, I have coral near them that is unharmed but I hear they can sting.
Use to have lots when I would get some new LR but them they seemed to died back after a few months, probably only a couple left. Don't think they were ever around my SPS but didn't seem to bother the Xenia. To get rid of them could try a smear of kalk paste over the area.
for the second pic look here (http://www.reefs.org/hhfaq/anemones/view) (Hydrozoan) and do a search

Wouldnt Kalk damage the GSP? The Hyrdas supposedly go away on thier own, and they dont seem to be bothering anything...just annoying spots on the glass.:biggrin:

Hydroids usually do go away on their own, the only thing I know they can absolutely devastate is dwarf seahorses.
