Unknown Gel Sac - ID Help

[siloxane]

Hello,

I noticed this gel like structure and was hoping to ID it with the help of our reef club. Any help would be very much appreciated.

some people call it red bubble algae. it grows with a "stalk" on the bottom. its best to try to grab the stalk and pull them out. if you burst the sack it will spread. i used to have bunchs of them until i got a rabbitfish. he has rid my tank of all of them.

Thanks Mike. I will see what I can do.

i always liked the red ones and would try to grow them on purpose. they never grew for me though.

They are very pretty. I really just wanted to make sure they are coral safe.
