Can someone help identify what this is????

Hello,

I noticed the other day that I have these white, sticky looking substances on some of my live rock and I'm trying to figure out what the heck it is. Is it a pest, disease, or.........? I had 2 snowflake eels die one after the other after only having each one for a week. So I'm trying to investigate and find out what's in my tank that could have killed them. I'm leaning toward parasites, but none of my other fish have been ill nor have they died. Any help telling me what this is would be great! Thanks

Aaron
