strange bubble forming on frogspawn
 

i have a small bubble forming on one of the heads of my frogspawn.. is it forming a new head or trying to heal some type of injury?

thanks for any help.

Posting a pic would help identify things better...

Normal. Seen it a few times before.

My hammer coral has done the same. While I wouldn't consider it normal because it happens rather seldom, it is nothing to be too concerned about. I do believe it is one method of individual heads commencing a split.

it is very similar to mikes hammer pic.. but not showing up so well on my cel phone cam... i will let it be as it seems to be not a big deal
