    IMG_2792.JPG IMG_2801.JPG Any ideas? It takes up all the places between the heads and create space, but doesn't cover the heads.

    Can you siphon any of it off? My zoas sometimes slime up and it collects debris.

    No it doesn't siphon off. It is "spongy" but it's weird how it's kind of smooth and solid and doesn't cover the heads.

    Looks like a q-tip or pineapple sponge. I get them occasionally when I have a slight rise in phosphates. Haven't seen them actually grow around a polyp though.

    And these are growing around a dozen or so polyps. In between and around -- but not over.

    I may gave this same thing in my tank. New setup, 2 months old, changing water every 2 weeks.

    Not harmful. Filter feeding on dissolved organics. Often show up in newer tanks
