    ID please!

    Can anyone tell me what this is? It has always been on my live rock, and it seems to be getting larger, but if it i a coral, I should probably know so that I can treat it properly. Thanks,
    Sara

    It has almost doubled in size in the past month, so whatever it is, it seems to be healthy. In the morning it seems to be covered in little tiny black dots, and in the evenings, the dots are smaller and white. I guess this means black dots=eating, white dots=sleeping?

    Yeah it definetly looks like a sponge, and a happy one too, if it is growing so fast. I don't know what the dots are, but most sponges are filter feeders as aquaman said and use their whole internal structure to siphon water through themselves to feed. some sponges also have an algea retarting chemical to keep themselves clean, maybe the black dots are algea starting to form and then at night it is killed...not sure

    Sponges are a sign of a healthy tank. Yours is a very nice color. I just get white or brown ones.
