sps experts. what is this!!!!!

i just noticed a bubble on one of my sps coral. i am attaching a pic so everyone can see. this is the first time i have seen it on a coral. did research on the internet and all i can come up with is coral tissue bubble.
as it is, it is a bubble on the tissue of the sps. at first i thought it could be a AEFW but the more i look at it it moves with the water flow and the bubble is spreading.
does anybody have any info on this? thanks in advance.

 

I have seen this before but I don't remember where or what you should do for it. I would be tempted to frag of the the portion of the coral with the bubble to isolate it.

 

There have been a couple threads on RC, no one ever nailed it down that I can remember.

On one of the threads the acropora was really affected and it eventually resolved after some time if I remember correctly.

I will see if I can find the thread, it was several months ago.

 

I agree, if you're worried about it, I would frag the piece off that has that and see what happens. If it works itself out you have a frag to trade, on the other hand if it ends up being something bad and kills it off, you wont lose the whole colony.

 

thank you to both of you. as always you 2 are always the first ones to chime in when needed.
i am on RC as the moment also and most of the morning looking for answers but unsuccessful.

 

thanks for the link corailline. as always you have been helpful and i thank you for being a part of 3reef.com.
