I had a similar sponge, known to me as Haliclona blue sponge. I bought it with necrosis, which continued very fast. I could be mistaken, but I believe that it caused the only tank crash I ever had. I wasn't exposed to the air in my presence, but after fragging it (already in a separate vessel) I had seen the largest channel, blocked by aragonite sand.
If I remember right, the ChilisREasy had growth of this sponge (have no link at hand, sorry), and others mentioned, that this is high light sponge. I kept it in sps tank.
