    Hi Guys, spotted this thing on my substrate this morning. Looks like a cocoon and feels a bit like a sponge. Its about length of a 10c piece. Any Ideas??? [​IMG][​IMG]

    Thx, Tony,Jacques and Keeyam. ANd now for the millions dollar question. What is the good the bad and the ugly on this guy? I've noticed some growing between my Zoas and some smaller ones behind my powerhead. Should I just leave them to grow?

    Very good sponge to have. It filters the water in your tank very well.. ;)
    I have not yet found a "bad" on these sponges....

    Yeah, was just reading up on some of the species and it says that they filter a lot of suspended nutrients & detritus from the water. Its amazing what will grow if you change something as simply as flow. Well, for now I'll leave the rest to do their thing.

    Dohn, on closer inspection I also noticed plenty of these guys in my sump. Hope they can help with my filtration. Any natural biological filtration I can get the better.:thumbup:
