    Looks like something i have in my tank. From what i have heard they are sponges not an algea. But maybe someone else can chime in and correct me if im wrong.

    Looks like sponges. Filter feeders, nothing to worry about

    I have some of those things. Something in my tank eats them every now and then... If you ever get a nudibranch I think that certain types only eat sponges... good to have around for them.

    I saw a huge colony of them on live rock in a fish store but I forgot to ask someone who worked there what they were, but they did look like sponges, any idea what causes them?

    They where probably just hitchhikers on your LR.

    Those are tunicates. I have a bunch of them in my tank too. They help absorb the nitrates and phosphates, they are good to have.
