Weird bubbles on frogspawn

I have had this frogspawn for about 3 months. It has been growing well and seems to be doing fine. However, each polyp has this weird bubble of tissue on it that I have never seen on anyone else's frogspawn.

Anyone know what is going on here?
 
I have the same thing! It means that the heads are splitting. Congrats, your Frogspawn are doing well! [smilie=lol.gif]
 
Awesome! They are doing better than anything else in my tank [smilie=smile.gif], even better than the xenia!
I bought this 3 months ago as 2 heads. Now I have 3 heads all splitting at once! I didn't notice that there were these bubbles before when one of the first 2 heads split. Thanks for telling me!
 
I bought a 4 head frogspawn and over the last 4 months its spawned 4 more heads and it looks like that everytime. It seems like they just grow way faster than anything in my entire tank.
 
Thats how it was in my tank too, until I went out of town and my air conditioning and ATO failed, killing about a fourth of my inverts, the frogspawns included :(
