Frog spawn. Does anyone know what the whiter areas are on my frog spawn stem? Seems happy otherwise, maybe the hermit crabs ?

Welcome to RC! That just appears to be the actual skeleton where the fleshband has receded. Not exactly abnormal as the coral grows.

Thank you for your help! I watch them so closely, I finally was able to get a better picture of that area. The frog spawn has definitely grown since I placed it in the tank. So that makes sense.
