Photosynthetic Plating Sponge?

[a;lksdjf]

I was browsing through LiveAquaria looking for a coral or something to round out my order to $100 (so I don't have to pay for shipping because I'm cheap like that lol) and I came across a photosynthetic plating red sponge that almost resembles a montipora coral and I was intrigued by it. Does anybody have experience with these? I would love to put one of these in my 15 g nano reef if it would allow for it.
