Tree Sponge

The Tree Sponge of the genus Ptilocaulis is normally red or orange. Its shape is very similar to that of a tree which includes a main trunk with several branches. The Tree Sponge requires a strong current and excellent water quality. All sponges, including the Tree Sponge, require some very special care in order to survive in the home aquarium. The most critical concern is that it never be exposed to the air. If it is, the air would become trapped in the maze of channels that line the inside of its body, blocking the path for planktonic food to reach its cells.
