Just got this frogspawn at RAP. First frogspawn for me. Are these baby heads coming out or some kind of hitchhiker? They are coming out of the calcareous base of the stem of the coral, not the fleshy part, which leads me towards hitch hiker. I assume the babies come from the fleshy part, but this is my first frogspawn so I have no idea. Help please and thank you!
