Dear Mirjam,

I can't be 100% sure but I suspect this is a colour form of Cuthona yamasui. That species has quite a range of colour variation and this could be a particularly orange form. C. yamasui is usually found feeding on stinging hydroids of the genus Aglaophenia, and I wouldn't be surprised if the hydroid colony in your photo is in the same or a related genus.  

Best wishes,
Bill Rudman
