SPLIT ANEMONE?

i have a rock & rose bubble tip anemone in my tank along with some other coral. i found this little guy on stuck to a rock and dont know what it is, my rbt has been acting funny for awhile could it be a baby rbt? or what could it be it might be too small to tell here is the pic...

It has been my experience that when the bubble splits you get two animals of almost equal size. You may have a majano in your tank. Do a search on the site or Google them and you will get more info than you care to know about these critters.
