When I first started this hobby a year and a half ago, there was a large white sponge about the size of a dollar coin on my live rock. Since that time, it has tripled in size. You may ask what this has to do with a sea squirt. The thing is, I have wanted a sea squirt for quite a bit of time but kept myself from buying one due to their feeding needs. However seeing the size of my sponge, I wonder wether I can perhaps keep the sea squirt thriving. Opinions? In case you are asking which one, I am thinking of the ink-spot tunicate.
