  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.

A 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.
