SPS bubble tissue disease?

[K-MAN]

So my tyree pink lemonade frag was set in a position where everytime i cleaned my tank i would end upo hitting the branches with my hand and chip some of the new growth. Well last month i noticed what appeared to be fluid filled sacs, almost look like transparent tumors, growing out of the main branch of the coral. The coral seems fine other then the growth. Today I noticed similar smaller growths on two other sps i have....has anyone ever heard or seen this in there tanks???????

I have a yellow tort that does this. Its my largest SPS colony and i've had it since i started the hobby in 04. Hasn't effected anything in 6 years.

I wouldn't worry.

I had two on my green slimer. They eventually burst and then closed over, no harm.

I noticed similar fluid filled sacs in a mystery orange acro when I first started keeping SPS about one year ago. At the time, I wasn't dosing anything except dkh when I performed water changes. My other sps seemed to be doing fine - maybe a bit starved for the correct water chemistry - but still growing normally. This acro did poorly in both my and my roommates tank, but once it was moved to his much smaller tank, it no longer got the fluid filled sacs on it. It was only recently, when I started tested for and dosing everything, that I realized the coral was starved for magnesium. Magnesium dosing caused the polyps/skin to regrow correctly. Magnesium levels weren't incredibly low, probably 1150-1200, but I hypothesize that this coral requires more magnesium to build it's skeletal structure. Without it, pieces are missing, the coral's skin doesn't correctly attach to the skeleton, and as a result, bubbles form.

The bubbles were about 1/2-3/4cm in diameter. In 12 months, they never spread to any other corals. I have pictures floating around somewhere. If you are interested i could try to dig them out.

Might be relevant: I probably broke the tips off of this coral more than a handful of times before the bubbles, but I have broken it many times since and the bubbles have not returned.

I have a green digi frag that has them. Been there a couple weeks. Digi does not seem to mind it. They are slowly getting smaller.
