One of the heads on my frogspawn has a big bubble right in the center, was told not to worry it's just splitting. It's been doing it for about a month now -should I be worried or do anything? Everything else about it looks fine. Curtis
Thanks for the post. I have also had these mystery bubbles appear on my frogspawn and hammer corals and didn't know what it was . I am very glad to find out that they are just spliting. Both of these corals have gotten hugh and I guess that must be the reason ....
