That is as close as I can get with it. It doesn't move or have any behaviors it just sits there like an egg. I touched it with the net and it seemed like the white outer coating is like a gel very soft but did not break apart. the center looks like it is filled with sand. I have a giant cup,torch,bubble coral, hammer,open brain, yellow leather, finger leather, purple mushroom, feather dusters,a ball sponge that is dieing, and star polyps. For fish right now just 1 green chromes, 1 fairy wrasse, 1 lyre tale antheas (female), 1 banded goby, and 4 clowns. also have a fire shrimp, 2 peppermint shrimp and various red and blue leg hermits, and snails. BTW
now it looks like it is starting to get buried under the sand.
