I found this sponge hidden in a darker part of the tank. In between some bubble that the crabs have not discovered. Its the trumpet graveyard down there. Those broken off pieces get enough light to live but not enough to grow. For size I had my flasher wrasse pose next to it. Seems to be covering about 2 inches of rock with just 1 opening in a portion that juts out. Its pink in color and at first I thought it was coralline. Now that it has an opening its prob a sponge. No luck with me duck-ducking it for an ID. Any ideas as for an ID?
