[heavenly_d3vi1]

I've just noticed that the front of my tank is covered in what i first thought were baby brittle stars... but upon a closer look I think they might be hydroid jellyfish! they sound scary, are they safe or do I need to get rid some how!?

I'm just gunna try and get a pic... just incase i cant, since its only a few MMs wide, heres a google image I found thats exactly the same for reference..

Yea those are hydroids, fairly common.
They have several different life stages, one as what you see there on the glass and also another as a polyp, where they look similar to yellow polyps.

Harmless

Cool, thanks nemo! do they sting? I'm a bit scared to put my hands in now!?

They're harmless to you. They don't get any larger than you see them now. You can wipe away the ones on the front glass, but they always end up finding themselves there again.
