As far as I know there isn't any creatures that eat it
I don't know how old your system is, but almost every new system has a red slime phase, I just got over mine and let me tell you, it was ugly, but it's part of the process.
It could just be part of the process of setting up a new tank, it is important to have a lot of flow in your system and most people say that RO/DI water is a lot less likely to get red slime than tap water.
I had tap water in my system when my bloom happened. The best thing to do is figure out why the red slime is there and do what you can to fix it that way (more flow, RO/DI water, etc). Other than that just ride it out, it will go away (mine took about a month though!).
Most people suggest against using any medication though.
good luck.
