Re: small white "bulb" hmmm...its hard to tell from that picture. does the white "bulb" change shape at all or open up? at first i thought maybe it was a small zoa that isnt opened up. if you are worried, i'd say snip it off, its only on 1 small piece, couldnt hurt. if you have another tank, you could snip it off and move it.
