Do you have a picture? If it is Callyspongia plicifera like the OP asked about years ago, then get rid of it. It is toxic. I tried one last year. It didn't make it two days past shipping. When I say it was dying, I went to remove it, I saw some clear stuff come off it, and the next day, 4/5 of my fish were dead. Beautiful sponge, but you don't want to keep it.Well i just bought one $ 45 and its hard to find any documentation about it . here's one that could help .

i have an NPS zone as well but i'm not sure this sponge goes there. Anyone have an idea because the tank i bought from was lith pretty good.
