I've got two yellow ball-like sponges or at least that's what the lfs told me was on the live rock I bought from them. But right now the largest one has a bulge on top of it and I've seen an air bubble. It looks like something is trying to get out. I'm seeing two/three white pimples pushing out. What is this? Is this how sponges reproduce or is this something else?
