Frogspawn bubble??

[JoeJoe]

I've had a frogspawn in my setup and all seems well in my 38 gallon. Over the past week or so, I've noticed a one inch bubble in diameter near the center of it...I believe close to one of it's mouths. Anyone have any idea of what's going on here? He's acting normal.....shrink when the lights go out and fully blossoms when the halides come on. Thanks for any input!!

JoeJoe,
I have a hammer that is doing the same thing. You'll probably notice the bubble getting larger over the next couple weeks, then shrinking back some. I've come to understand that this means the head is splitting. So far two of the branches on my hammer have shown this behavior and the heads have split. Hope that helps!
