is this normal?

this is my first saltwater tank and i have noticed that this cotton ball-like has been growing live rock, is this normal, i am trying to figure out why my fishes are getting infected.

Can you get a clearer pic? What are your fish look like, how do you know they are infected?

is the white stuff real slimy ? I am not sure of what it is , but I cleaned up you pic a little so others can get a better look

hey thanks for helping me out snake and fish. i can tell they are infected by looking at their eyes and usually i see a white substance on there eyes and i put them in my hospital tank for like three days and it takes care of that problem.
