Noticed this thing hanging under a piece of live rock in my tank. I hope its fairly new, would hate to think I missed something this big in my tank considering the amount of time I spend looking. Anyway, its about 2.5 inches long 1.25 around and feels kinda delicate but not soft nor slime covered. Any ideas? Kinda looks like a giant pineapple sponge. Oh and its white, sorry about picture quality, its from my iphone.
