I picked this up at the swap . At first I put it low figuring it would be low light like most sponges . It really didn't do much so I moved it into better lighting and more flow . That seemed to do the trick . It is opening up real well now and "shedding" off the brownish algae skin that had covered parts of it . The colors look real nice in person, a nice bright orange with pure white polyps . Enjoy the Photo.
How small is that?
