Hi Julie,

I've been doing coral research on Curacao (NA) the last 2.5 years which involves diving everyday. What you describe, I haven't seen on my dives. Strange, since Bonaire is virtually around the corner. 

Cheers, Sander

    >Greetings Coral List,
    >While diving in Bonaire this month I noticed small white growths on
