These two things I noticed on the stalk/rock frag of some frogspawn when I bought it a few months ago. Only now do I have it out in the open where I can see it better. The top I looks to me too symetrical to just be nothing, but maybe my imagination. The bottom has definitely grown from one circular polyp/head to the three currently - still slightly smaller than a dime. I don't know what either are...

The second photo is a much better representation of the true color.
