I have
never had a tank that
once live rock was introduced a wide variety of sponges did not appear
seemingly out of no where, in just about every color and shape
imaginable. Most are transitory, making an appearance and shortly
disappearing again. Most likely our systems are lacking the proper
environment for their long term success. Sponge and Tunicates also seem
to be a difficult animal to introduce as a single store bought
specimen, very few hobbyists have success with them, although as more
systems are kept with much more naturaly occuring filtration methods,
that is slowly changing.

wide assortment of sponge species can be found on a single live rock
You may notice
that the sponges
are not named, this is simply because it is all but impossible to
correctly identify these animals, even those who study them for a
living have a difficult time. Although a few common names are used,
such as the pineapple sponge (top row, center) even those names are
mixed up frequently.
