So I was just feeding my fish and noticed these white curly things that seemed to be attatched to my firefish right behind his fin. After doing some research I determined that they were eggsacs of an internal parasite that resides in fire fish. Here is the link to the site, scroll down until you see pictures of a purple fire fish. Marine Fish Diseases and Parasites And here is mine: Has anybody had these on their fish before? Is there any way to get rid of it? will it kill my fish? and will it spread to any others? I know the site said that it usually doesnt, but I am worried about it.
