Thanks in Advance - 2 quick...? questions, Scler. recruitment   11/17/2008
Gang (think that covers both genders),
<Okay>
I have 2 questions I was hoping you could shed some light on. The first is a mystery that seems to be repeating itself. I first noticed about 9 months ago that I had what looked like 1 -2 small pink Pocillopora (sp?)
<Mmm, Pocillopora?>
polyps growing on my return. High up many feet from my colony. I thought it was odd. About a month or so after that I saw a path growing on two other rocks also a good distance from that. Again after some time I saw a patch growing on my glass of my tank on the opposite side of the other action. Now I have a 2-4" multi arm colony growing on 2 of my rocks,
<Usually discoid...>
on my return, a 2 inch disk growing on the glass and notice that at the water line along the back of my tank, on other live rock and on different sections of my returns I have new little growths... My question is what is going on?
<Asexual repro.? Or... possibly another organism/species... phylum altogether>
If it was already on the live rock, fine, but not the glass of my tank. If was displaced when I had an algae issue and was scrubbing rock a year ago, OK, but how is it spreading now? Is it reproducing?
<Or just growing...>
I can't imagine that. Could my urchins be spreading it?
<Mmm, doubtful>
I am at a loss... a happy loss, but thought I would ask.
<A photo (or three) please... something close up, well-resolved...>
My second question is star polyps... They are getting close to my corals and onto larger rocks I don't want to pull out... can I control them or should I get the out now before it is too bad?
<Up to you... there are many instances of adaptation twixt Clavulariids/Stoloniferans and other Cnidarians... learning to "get along" well enough... but if it were me/mine... I'd keep them separated...>
(ok worse.) Also where they are on big rocks can I fight back? Who will win when they hit my birds nest?
<The Polyps>
Tooth coral?
<Here too>
Lastly, since I am cleaning them out. I put some on the back wall of the tank (on the glass) it too is spreading. Should I get rid of that too?
<Up to you...>
Thanks, counting the number of question marks, I think I may have exceeded two....
Jim
