Yes, clatharina sponge. I have a bit in my tank and have begun injecting them with vinegar to thin them out

A lot of different creatures are showing up in my aquarium. Yesterday I spotted a corynactis, but when I touched it, it just fell apart.

I like ornamental sponges. Also, cryptic sponges are useful for biochemistry.
