That first pic, whatever it is, is so round I wonder if it is algea. On the bubble algea try to siphon that up on your next PWC and the third pic is great. I love gobies.

Does the algae seem to be soft or is it encrusting the rock?

Looks to be Lobophora algae, the first pic?

Just looking at your bubble algae makes me mad. I'm in an all out war against my bubble algae.... The pic of the goby is great though. We do love pictures!

I do believe innovator is right, what are the odds. lol Check these links for other pics to compare yours too.

Those links are similar except the photo in the links look as if they are coming off the rock like a plant or mushroom. This is just like a rock covering I felt it and it feels just like a smooth spot on the rock and is totally attached to the rock and totally circular.

I found this database of algae it has every type known I believe nothing is really all that similar the Algae page
