    Hello everyone ;),

    So i've had this wierd thing hanging from the rocks in a cave in my reef tank. I really dont know what it is, but for me it looks like some sort of sponge. But what is it? If its a sponge, what species do you think it is? This picture is pretty precise, but to describe it better: Its yellow, kinda fuzzy and round. It has been in my tank for quite a long time now. It doesnt seem to do any damage what so ever, but i want to be sure, and its funny exploring the live rock in your tank :) So what is it?: (Picture coming very soon)
