Saltwater is so strange and cool!

You probably have the right conditions for their growth and maybe he didn't. I know when I switched tanks a couple of years ago, many of the rocks were bound together with a white sponge that I had never seen in the tank before (it was only between the rocks) and I haven't seen it since. Currently I have little bits of yellow, some different white and some purply blue sponges in my tank. Pretty neat.
